GEORGE CROOM ROBERTSON ABERDEEN UNIVERSITY PRESS. PHILOSOPHICAL REMAINS OF GEORGE GROOM ROBERTSON GROTE PROFESSOR OF PHILOSOPHY OF MIND AND LOGIC UNIVERSITY COLLEGE, LONDON WITH. A MEMOIR EDITED BY ALEXANDEK BAIN, LL.D. EMEBITUS PROFESSOR OF LOGIC, UNIVERSITY OF ABERDEEN AND T. WHITTAKEE, B.A. (OxoN.) WILLIAMS AND NOEGATE 14 HENRIETTA STREET, COVENT GARDEN, LONDON AND 20 SOUTH FREDERICK STREET, EDINBURGH 1894 PREFATORY NOTE. THE present volume contains a collection of the more important philosophical writings of the late Prof. Groom Robertson. Outside this work, besides his volume on Hobbes, there remain his historical articles in the Encyclopedia Britannica on Abelard and Hobbes, his biographies of the Grotes in the Dictionary of National Biography (George Grote, his wife and two brothers — John and Arthur) and other minor contributions to various periodicals. The memoir is brief and comprehensive rather than minute. It has been somewhat extended by insertions of importance, as will be seen in their places. The arrangement of the volume, and its super- intendence through the press, devolved mainly upon Mr. T. Whittaker. Mr. Whittaker had long been Robertson's assistant in preparing critical and other notices for Mind. The only deviation from full and literal reproduc- tion of the papers is in the case of the first — which is an abridgment, by Mr. Whittaker, of Robertson's inaugural lecture in University College. This lecture is of special interest, as showing how well he had mapped out the ground that he eventually occupied in his philosophical teaching and writing. The Editors have to acknowledge the courtesy of Messrs. A. & C. Black, in freely according permission to reprint the author's philosophical contributions to the Encyclopedia Britannica. A. B.

GEORGE GROOM EOBERTSON was born in Aberdeen on 10th March, 1842. During the earliest years of infancy, he was con- stitutionally delicate, and, partly on this account, and partly not to stimulate a brain that already gave signs of unusual activity, he did not commence his education till he was six years of age. He was sent first to a dame's school. He mastered the alphabet and learned to read in an astonishingly short time. After a few weeks of this elementary training, he was transferred to the school maintained by the Incorporated Trades, then under the charge of Mr. Eoger, — -a teacher of some note in his day and a fine specimen of the schoolmaster of the olden type ; being as thorough and exact a teacher as he was a strict disciplinarian. The subjects he taught were reading, writing, arithmetic, geography, English composition, and Bible knowledge under the guidance of the Shorter Catechism. Having spent four years under this regime, Robertson went on, at the age of eleven, to the Grammar School, — where, for the first three years of his course, he was under the tuition of Mr. John Brebner, now Superintendent of Education in the Orange Free State, South Africa. During his fourth year, he was taught by the rector, Mr. Thomas W. Evans. At the Grammar School, the principal topic was Latin, to which were added English (chiefly history) and the elements of Greek. George proved so apt a pupil that, not only did he carry off prizes (some of them firsts) at the several annual examinations, but, at the end of the fourth year, while there was still a year of the usual curriculum to run, he gained by competition the second bursary at Marischal College and University, — which, accordingly, he entered as a student in November, 1857. The first winter was occupied with Greek, under Prof. E. J. Brown, then an elderly man but a not inefficient teacher ; Latin, under Eobert Maclure, a man of a fair schoolmaster type, with the genius of translation. At the end of the session, Eobertson carried off the second prize in Greek, and stood eighth in Latin. X MEMOIR. Second year — Higher Classes in Greek and Latin ; Mathematics, under Dr. John Cruickshank, a teacher of the first order ; and Natural History, under James Nicol, the well-known Geologist. At the end, his prizes were — Greek, first ; Latin, fourth ; Mathe- matics, eighth ; Natural History, fourth. Third winter — Senior Mathematics ; Natural Philosophy, under James Clerk Maxwell, and a voluntary extra class in Greek. At the close, he stood — Mathematics, seventh ; Natural Philosophy, twelfth ; Greek, first. At this point, occurred the great revolution in the Aberdeen colleges, by which they lost their individuality and were trans- formed into one institution — the United University of Aberdeen. As there were • duplicate professors in all the Arts subjects, the elder of the pair was superannuated and the work carried on by the younger. The winter session, 1860-61, was the first under the new system, with this qualification, that students who had commenced their courses in the separate colleges were allowed to finish under the regulations previously in force in each. In Robertson's case, all that remained obligatory was to attend the Moral Philosophy Class of Prof Martin, the former Marischal College Professor, now retained in the United University. The new programme of subjects included, for the first time in Aberdeen, a separate chair of Logic, attendance on which was to be compulsory only on students now entering the United University. Nevertheless, the class was actually formed, although attendance could not yet be made obligatory. Robert- son attended it voluntarily ; and this was the first occasion of my coming into contact with him. He took a high place in the examinations, and at the same time distinguished himself in the class of Prof. Martin. He took the M.A. degree with highest honours, in April, .1861 ; his leading subjects being Classics and Philosophy. In October of the same year, there were instituted the Fer- guson Scholarships, of the value of £100 a year for two years, open to graduates of all the four Scotch Universities. One of the two was for Classics and Mental Philosophy combined. Robertson competed for this and was successful. My more particular intimacy with him commenced in the months of his preparation for the competition. The examiner in Philosophy was Dr. McCosh, then Professor in Belfast. It was a condition of the scholarship that the successful candidate should for two years pursue a course of study under the direction of the Trust ; MEMOIR. XI and Prof. McCosh was appointed to give the requisite direc- tions in this instance. Robertson at once availed himself of the fund at his disposal to pursue his studies on a very wide scale. The winter of 1861-2 was spent by him in London, where he attended selected classes in University College ; one being Prof. Masson's senior class of English Literature, in which he gained the second prize. He 'also attended Maiden's Senior Greek, and the Chemistry class of Prof. Williamson. In July, 1862. he proceeded to Germany. His first resort was Heidelberg, where he stayed eight weeks ; his principal occupation being mastering German. It was to Berlin that he looked for the fullest scope to his curiosity in the wide domain of philosophical and other learning. He reached the German capital on the 24th of September, and remained till the latter end of March — a period of five months, which included the winter semestre at the University. He attended two classes of Trendelenburg — one in Psychology, four hours a week ; one on the Metaphysics of Aristotle, two hours a week ; Du Bois Rey- mond, Physiology, five hours a week ; Althaus on Hegel, one hour a week ; Bona Meyer on Kant, two hours a week. He paid frequent visits to Dorner, and afterwards kept up a friendly correspondence with him and with Trendelenburg. He also saw Lepsius at his house, and, on leaving, was presented by him with a copy of his Royal Dynasties of Egypt. He maintained, at the same time, a sedulous course of reading, devoting himself more especially to Kant. Leaving Berlin, he made a tour in Eastern Germany on his way to Gottingen, where he remained two months. He attended Lotze on Metaphysics and Rudolf Wagner on Physiology. With both these he had subsequent correspondence, and obtained from Wagner a letter of introduction to Broca in Paris, whither he now directed his course. He arrived on the 24th of June, and continued there till the 10th of September — a very busy time, but details are wanting. He was recalled to Aberdeen by the intimation of a vacancy in the Examinership in Philosophy, but that he failed to obtain. He now remained at home, devot- ing himself to philosophical study. It was during the year following his arrival that I obtained his assistance in revising The Senses and the Intellect for a second edition. He elaborated a number of valuable notes from his German studies, — such as the addition made to the handling of the muscular sense. Also, for The Emotions and the Will, he contributed the classifications Xll MEMOIK. of the Feelings prevalent in Germany,— those of Kant, Herbart, and their followers; and in other ways aided in the revision. After bringing out the second edition of those two volumes, I was occupied for some time in preparing a Manual of Ehetoric. For this he compiled the Classification of the SPECIES OF POETRY and VERSIFICATION. He, likewise, co-operated with me in mak- ing a search for suggestions and illustrations in Aristotle's Ehetoric and Quintilian's Institutes. The result, however, was disappointing ; extremely little could be discovered in either for adaptation to a modern manual. In September, 1864, he was appointed teaching assistant to Prof. Geddes, and shared with him the work of his Greek classes. He performed the same duty for session 1865-66. The remuneration was £100 a year, and no duty was required during the seven months' vacation. He was able, therefore, to devote himself largely to philosophical work. In 1864, he wrote an article on German Philosophy for the British and Foreign Evangelical Review, which appeared in the July number. He also wrote an article on Kant and Sweden- borg in Macmillan, for May, the same year. In the summer of 1866, a vacancy occurred in the Chair of Mental Philosophy and Logic in University College, London. After an abortive attempt on the Chair of Philosophy in Owen's College, Manchester, Robertson became a candidate for this vacancy. His chief rival was Dr. James Martineau, whose cause was espoused with great energy by one section of the Council, while another section, under Crete's leadership, favoured Eobertson. The leading incidents of the struggle are given with official exactness by himself in his life of Grote in the Dictionary of National Biography. The election took place in December, and he opened his class in January, 1867. His residence henceforth was London. Before he left Aberdeen, I obtained still further assistance from him towards the Manual of Ethics, forming part of Mental and Moral Science. His contributions were — The Neo-Platonists, The Scholastic Ethics, Hobbes, Cumberland, Cudworth, Kant, Cousin, and Jouffroy. He had no further hand in the Manual except in revising some portions of the proofs. Not long after being appointed to University College, he con- ceived the project. of a work on Hobbes ; for which Grote gave him every encouragement, and wrote to the Duke of Devonshire to procure for him access to the MSS. preserved in the family seats. As usually happens, this design proved more laborious MEMOIR. Xlll and protracted than was at first imagined. In addition to the labour that might naturally be counted upon, an unexpected difficulty was encountered in connexion with Hobbes's mathe- matical writings. It seems that in Molesworth's edition these were very carelessly edited. In order to do justice to the hot and lengthened controversy between Hobbes and Wallis, he had, at considerable pains, to resuscitate his mathematical knowledge and to trace out the sophistical reasonings of Hobbes through all the disguises that his ingenuity enabled him to put on. One portion of his researches on the biographical part ap- peared in the Encyclopedia Britannica, and the completing section of the biography, together with a survey of the writings, came out in the volume in Blackwood's Philosophical Classics. Although this work was not executed on the scale originally projected, it preserved the most important part of his labours, and is duly appreciated by students of philosophy. His enlarged purpose would have included more copious reference to the great contemporaries and precursors of Hobbes, whom he had studied with no less care, and to whom he might have done justice in other forms had he been longer spared. For his elementary lectures at the College he prepared, with all due painstaking, courses of Logic, deductive and inductive, systematic Psychology, and Ethical Theory. All through his career his attention was nearly equally divided between the elaboration of philosophical doctrines according to their most advanced treatment, and the history of philosophy both ancient and modern. The summer courses at University College, which were adapted to the requirements of the M.A. degree at the University of London, generally took him into fresh ground — the ancients and the moderns alternately — and were the occasion of a special study of the original authorities. His accumulated stores of historical material were thus very great, as his publica- tions from time to time made manifest. A few more years of active vigour would have enabled him to leave a monument of the history of philosophy second to none. His doctrinal clearness was a notable and pervading characteristic of all his expositions of foregone thinkers. He delivered some carefully prepared popular lectures at Manchester, Newcastle, and the Eoyal Institution, London. One subject was "The Senses"; another "Kant," on whom he gave a course of four lectures at the Eoyal Institution in 1874. His introductory lecture at the College for October, 1868, appeared XIV MEMOIR. in the Fortnightly Review. Other topics of popular lecturing were "The English Mind," "The History of Philosophy, as preparation for Descartes," and " Locke". He gave for several years the philosophical course to the College of Preceptors. From 1868 to 1873, and again from 1883 to 1888, he was Examiner in Philosophy in the University of London. His examination papers are sufficient proof of his efforts to do justice both to the subjects and to the fair expectations of candidates. He also acted as Examiner in the University of Aberdeen from 1869 to 1872, and from 1878 to 1881. He examined for the Moral Science Tripos, Cambridge, in 1877-78, and for the Victoria University, Manchester, as one of the original staff. He was engaged by Dr. Findlater, editor of Chambers's Encyclopedia, to furnish contributions to that work. When the Messrs. Black projected their new edition of the Encyclopedia Britannica, they invited Findlater to become their editor. He declined the task, and suggested a choice between Thomas Spencer Baynes and Eobertson. When Baynes entered on the work, he engaged Eobertson as a contributor in Philosophy. The articles actually written by him 'were Abelard, Analogy, Analysis, Analytic Judgments, Autonomy, Association, Axiom, Hobbes. Baynes had also bespoken from him the article Psychology ; which he undertook, intending it to be on historical lines. When the time came near, he found himself unequal to the effort and recommended James Ward in his stead, — a fortunate arrange- ment as it turned out. On the death of Grote in 1871, he had the principal share in editing the Posthumous Work on Aristotle, which occupied him the autumn and winter of that year. From the distinctness of the MS., this was, in one respect, not a difficult task, although involving a considerable expenditure of time in revision. What chiefly made it toilsome and anxious was a want of exactness on Grote's part, through some defect of vision, in entering the numerical references to the text. Every one of these had to be carefully verified from the originals. The result was a master- piece of correct editing ; and the work as thus brought out will deserve to be ranked as an editio princeps of Grote's monograph on the Stagirite. The death of Grote brought out the fact that he had left to University College a sum of £6000 as an endowment to the Philosophy Chair. Mrs. Grote, who was entitled to the life in- terest, surrendered the amount in 1875, two years before her death. MEMOIR. XV In the year of the publication of Aristotle, 1872, Eobertson married Caroline Anna Crompton, daughter of Justice Crompton. She was in every sense a helpmeet ; having the same views on the higher questions of life, and being an earnest labourer in the public questions that he also had at heart. She was likewise of service in his official work, when his strength became barely equal to its routine. Kobertson was a member of the Metaphysical Society of London, which flourished for several years and drew together a remarkable mixed assemblage of philosophers, politicians, and ecclesiastics. He contributed a paper on the 13th of May, 1873, on " The Action of so-called Motives ". This paper was reprinted in Mind, vol. vii. p. 567, and is one of our best handlings of the Free Will question on the basis of a critical examination of the verbal improprieties that obscure the issue. In 1880, when I resigned the Logic Chair in Aberdeen, he was by general concurrence my destined successor. So much was this felt by aspirants to the office, that, until he declared his resolution on the subject, no other candidate entered the lists. Only after he made up his mind to remain in London was there an open competition. In 1874, I broached to him the founding of a Quarterly Journal of Philosophy ; explaining my notions as to its drift, and asking his opinion of the project. My desire was that he should be editor in the fullest sense of the word ; and, on that condition, I undertook the publishing risks. After full consideration he approved of the design, and accepted the editorship on the terms proposed to him. The subsequent steps necessarily were to obtain the concurrence and approbation of active workers in the field. I first approached Mr. Herbert Spencer, and found him cordial in favour of the scheme. I next saw Messrs. Venn and Sidgwick in Cambridge, and obtained their full concurrence and promise of support. Other parties were seen by Eobertson, or corresponded with, both in England and in Scotland. The amount of encouragement was such as to decide us in organising the work for speedy publication. We at first thought that it might be brought out in the course of the following year, 1875; but as it could not be ready in the beginning of the year, it was finally arranged that the first number should appear in January, 1876. Eobertson bore the brunt of the requisite preparations for the start ; settling the plan and arrangement of the numbers, procuring the requisite pledges of articles in advance, and XVI MEMOIR. drafting the programme. It was his happy inspiration that gave the title, which commended itself at once to every one. Our earliest success was the series of papers on Philosophy in the Universities. We had the good fortune to lead off with Mark Pattison on Oxford, and to secure admirable represen- tatives for the others in succession ; Eobertson himself supplying the account of the University of London. Another matter that we had set our hearts upon we did not succeed in, — viz., to set going a series of discussions on the conduct of Examinations in Philosophy. Perhaps, either of ourselves ought to have broken ground ; but, as we did not do so, many other contributors naturally have felt shy at an operation involving criticism of one another's published examination papers. Nevertheless, the subject is one pre-eminently suited for a free interchange of views. The enormous number of questions set every year in the depart- ment of philosophy, in connexion with the conferring of degrees and otherwise, by exhausting leading questions tempts examiners to select out-of-the-way and recondite points which do no justice to the candidate's natural course of study ; an evil that ample discussion might be able to remedy. It was of course a prime object of the Journal to keep the English reader an courant with foreign publications in the philosophical field — both set treatises and periodicals. In this last region, most important aid was given at the outset by Prof. Flint, of St. Andrews, — which he was obliged to discontinue on being appointed to the Theology Chair in Edinburgh. The editor spared no pains to procure contributions of a like nature, and took upon himself a large part of the burden of supplying the desideratum. Indeed, in every department of the work of the Journal, it is unnecessary to say that he had always the lion's share. Now that he is gone, it is a satisfaction to think that, besides contributing largely to the review of novelties from every corner, and expounding the great historical names of the past, he communicated his most advanced re- flexions upon many leading questions in psychology, philosophy, and logic. It is perhaps unnecessary for me to say more, con- sidering that the result is accessible, and that the collective body of contributors have recently given expression to their estimate of his merits. It would, however, be an omission on my part, not to express the deliberate opinion formed on sixteen years' experience, that I regarded him as, in every point of view, a model editor. MEMOIR. XV11 Twelve years before his death, his fatal malady began to show itself. On discovering the serious nature of the attack — calculus in the kidney, — he set himself to work to parry its advances by every form of precaution and self-denial that his skilled advisers and his own experience could suggest ; being aided by the un- remitting devotion of his wife. How such a malady could have got possession of him at the age of thirty-eight, it is needless to speculate. This much we can pronounce, after the event, that the strain of his intellectual application from early years was excessive. His persistent labours were aggravated by a fervour of manner which, though raising his value as a public teacher, involved a nervous expenditure that even a naturally healthy system could not well afford. During sessions 1883-4, 1886-7, and part of 1887-8, he had to employ substitutes for his teaching work. He had given in his resignation in April, 1888; but the Council declined to accept it, until he should have the relief of another session by means of substitute. He finally resigned on the 7th May, 1892. He threw himself with the utmost zeal into the business management of the College, first as a member of Senate, and latterly as one of the Senate's representatives on the Council . Not long after his appointment, Grote learned with great satisfaction that he was highly esteemed among his colleagues in the Senate for his judgment and energy in business matters. In the larger sphere of the Council's operations, he promised to make himself extremely serviceable, when his failure in health obliged him to withdraw from being a member. His colleague, Prof. Carey Foster, has furnished an estimate of his character and active co-operation in the business of the College, first in the Senate, and latterly in the Council. I give it in his own words : — " For some time after his appointment as Professor, he was not a frequent attendant at meetings, being presumably occupied with the work of his Chair, and leaving general questions to the management of his older colleagues. " His great value was very much in the part he took in dis- cussion. Here he was always ready, clear, and to the point. Of course, in connexion with the business of such an institution as University College, it will often happen that proposals are made which, for some reason or other, are distinctly undesirable, but which it is not easy to meet in an effective way on the spur of Will MEMOIR. the moment, at least not without taking an attitude of personal opposition to the proposer. In such cases, I have often been very much struck with Robertson's quickness in seizing the proper ground of principle to be adopted in considering the course proposed. Generally, almost always, I am happy to say, he and I were closely agreed in our views ; but, while I might be casting about to find the right way of meeting a proposal I disapproved of, the opportunity for useful opposition would often be gone. Eobertson, on the other hand, would cut in at once with exactly the right consideration of general policy to which all were ready to agree. "He was Dean of the Faculty of Arts and Laws for the Session 1871-2, and of the Faculty of Science for the Session 1880-1, and 1881-2. This is an office which involves a very considerable amount of attention to current working details, and Eobertson discharged it on both occasions with great efficiency and assiduity, but I do not find any special records of importance. " In 1883 a matter occurred which, at the time, created a good deal of feeling, both in the College and in some circles outside. This was the refusal of the Council to admit Mrs. Annie Besant and Miss Alice Bradlaugh to the Class of Practical Botany. I think there is no doubt that the Council acted within their legal power in this case, but many of us, Eobertson very decidedly, disapproved of their action, and felt that it was not only inex- pedient but opposed to the spirit of our traditions. " In 1886, for the first time, Professors were admitted (first at three, afterwards, in 1888, six) to serve on the Council of the College. Eobertson was selected by his colleagues on the Senate as one of their first three representatives. He held office for four years, and, while health lasted, was very assiduous in his attention to the business of the Council. In particular, he took an active part in the discussions that arose on the drafting of the Charter of the proposed Albert (afterwards Gresham) University. He was a member of the Special Committee charged with the matter, and strove energetically to give to the scheme at once a more liberal and more academic character than it eventually assumed. If his health had allowed him to make still greater exertions, perhaps this scheme would have had a different issue." By help of extracts from the minutes of the Senate where Eobertson's name appears, some further particulars may be MEMOIR. XIX gleaned as to his lines of activity. In particular, with reference to the admission of women into the classes in which University College took the lead, he bore a prominent part. In the various steps by which the final result of mixed classes in every depart- ment was arrived at, he was a chief spokesman and adviser. It was on 23rd April, 1869, that he moved appointment of a com- mittee "to consider the expediency of admission of women to classes in University College ". A report presented 4th May recommended that classes for ladies in physics and chemistry, in connexion with the Ladies' Educational Association, be held in the College next session. This meant that the Professors should repeat their courses to women exclusively ; a necessarily burdensome imposition upon the teaching strength of the College. The Professor of Political Economy, Cairnes, having represented himself as unequal to a duplicate course, was allowed to teach a class of men and women mixed. The mixing gradually extended to other classes ; the years 1877 and 1878 saw the final admission of women into the classes generally, Eobertson being on the Com- mittees that promoted the achievement. In his own class, female students were latterly in the majority. He repeatedly sat on Committees of Senate for recommending appointments to vacant chairs ; as, for example, Mathematics (De Morgan resigned, Hirst appointed), Applied Mathematics and Mechanics (Clifford appointed), Political Economy (Cairnes resigned, Courtney appointed), Greek (Maiden resigned, Wayte appointed). Acting under the lead of John Stuart Mill, he entered zealously into the movement in behalf of women, and was from December, 1870, to December, 1876, a member of the Committee of the London National Society for Women's Suffrage. A brief account of the movement will serve to show Eobertson's connexion with it, more particularly as the recipient of letters from Mill. In the spring of 1871, serious differences of opinion among the workers for the movement becoming evident, proposals were made for the formation in London of a new Committee- — which, when fully organised, assumed the title of ' Central Committee of the National Society for Women's Suffrage,' and desired to affiliate to itself all existing Societies for Women's Suffrage. From the first, the chief ground of antagonism between the two Committees (the London National and the Central) was diversity of opinion XX MEMOIE. concerning the agitation against the C.D. Acts. Those engaged in the agitation at no time proposed to use, for their purpose, funds subscribed for the promotion of Women's Suffrage ; but many of them did seek and claim perfect freedom to assert, at Women's Suffrage meetings, that the repeal of the C.D. Acts was one of the objects for which the suffrage was desired. And they saw no reason why the same persons should not be prominent in both agitations. Although Mill, in common with Eobertson, disapproved of the C.D. Acts, and, on one occasion, denounced them at a Women's Suffrage meeting, he became fully convinced that the association of the two questions would have a most injurious effect on the prospects of the Women's Suffrage movement. With his cordial approval, the Committee of the London National Society declined to connect itself with the new Central Committee, and Mill shortly afterwards gave his name as Hon. President. Eobertson took a prominent part in the discussions which led to this result, was in constant correspondence with Mill on the subject, and, until Mill's death in May, 1873, continued to be the medium of communication between the Committee and its Pre- sident. After Mill's death, he was less actively engaged in the work of the Committee, though he still frequently attended its meetings. When, in the winter of 1876, Mr. Forsyth, who had been the parliamentary leader of the movement, since the general election in February, 1874, was succeeded by Mr. Jacob Bright, Eobertson, along with several of his associates, retired from the Committee. Thenceforward, while his opinions, I understand, remained un- changed, he took no part in the Women's Suffrage movement. A notice of Eobertson that appeared in the Spectator, 1st October, 1892, by his most intimate friend Mr. Leslie Stephen, is the best conclusion to the sketch of his life, and saves me from much that would be necessary to do justice to him. In point of exactness of appreciation and felicity of statement, it would be vain in any one to rival the delineation thus afforded. " I hope that you will permit me to say a few words about the late Professor Groom Eobertson. I had the great happiness of an intimate acquaintance with him during the later years of his life, and can mention some facts which ought, I think, to be known to all who may have been MEMOIE. XXI interested in his work. Every serious student of philosophy is aware that Prof. Robertson was an accomplished meta- physician and psychologist. I do not suppose that there are more than two or three living Englishmen whose knowledge of those subjects is comparable to his for range and accuracy. He had given up his whole life and energy to such studies from very early years, and whatever he did, he did thoroughly. My own knowledge only enabled me to appreciate his acquirements within a comparatively small circle ; but whenever I applied to him for advice and information, I was surprised afresh by the fulness of his knowledge. He had always considered for him- self any question that I proposed to him, and knew what was to be found about it in previous literature. My own experience was confirmed by those who were better judges than I could be. It was impossible to consult him without being struck by his command both of the history of past speculation and of the latest utterances of modern thinkers. His judgments, whether one accepted them or not, were at least those of a powerful, candid, patient, and richly stored intellect. He has not, indeed, left much behind him to justify an estimate which will, I think, be accepted by all who knew him. His excellent monograph upon Hobbes, and a few articles, chiefly critical, in Mind, are, I fear, all that remains to give any hints of his capac- ity. For this want of productiveness there were, unfortunately, amply sufficient reasons. Robertson was, in the first place, conscientious almost to excess as a worker. He could not bear to leave undone anything which was necessary to secure the utmost possible precision. He would not write till he had considered the matter in hand from every possible point of view, and read everything at all relevant to his purpose. As editor of Mind he expended an amount of thought and labour upon the revision of articles which surprised any one accustomed to more rough-and-ready methods of editing. Besides correcting mis- prints or inaccuracies of language, he would consider the writer's argument carefully, point out weak places, and discuss desirable emendations as patiently as the most industrious tutor correcting the exercises of a promising pupil. Contributors were sometimes surprised to find that their work was thought deserving of such elaborate examination ; and it often seemed to me that he could have written a new article with less trouble than it took him to put into satisfactory shape one already XX11 MEMOIR. written, with which, after all, he perhaps did not agree. He never reviewed a book without thoroughly making himself master of its contents. He applied, as I have reason to believe, the same amount of conscientious labour to the discharge of his duties as Professor. His work in the two capacities absorbed, therefore, a great proportion of his disposable energy. So con- scientious a worker was naturally slow in original production. He would not slur over any difficulty in haste to reach a conclusion. Robertson, indeed, like most of us, had some very definite opinions upon disputed questions, and belonged decidedly to what is roughly called the empirical school. But, whatever his views, he was always anxious to know and to consider fairly anything that could be said against them. Had he ever been able to give a full exposition of his philosophical doctrines, the last accusation that could ever have been brought against him would have been that of hasty dogmatism. He might have failed to appreciate the opposite view ; but the failure would not have been due to any want of desire to understand it thoroughly. He was always anxious that Mind should contain a full expression of all shades of opinion. Whether he succeeded in this is another question. An editor can open his doors, but he cannot compel every one to enter. I can only say, from my own knowledge, that he did his best to secure the co-operation of the men from whose views he most decidedly dissented. " There was, however, a cause for want of productiveness more melancholy and more sufficient than those of which I have spoken. When I first knew Robertson, he told me that he was preparing a book upon Hobbes. It would have included an estimate of the whole philosophical movement of the seven- teenth century. He had gone into all the preparatory studies with his usual thoroughness. He had examined the papers preserved at Chatsworth ; and had at his fingers' ends all the details of the curious and obscure controversies in which Hobbes was engaged with the mathematicians as well as with the philosophers of his time. When I wrote for the Dictionary of National Biography a life of Hobbes, which was in substance merely a condensation of Robertson's monograph, supervised by Robertson himself, I was astonished by his close acquaintance with all the minutiae of the literary and personal history of the old philosopher. Unfortunately that monograph was itself only the condensation of knowledge acquired with a view to his MEMOIR. XX111 larger work. He was obliged to abandon the original scheme by the first appearance of a cruel disease from which he was ever afterwards a sufferer. He had to submit to painful opera- tions, which severely tried his strength. Though temporary relief might be obtained, he lived under the constant fear of renewed attacks, and was forced to observe the strictest regula- tions for the sake of his health. It was not surprising that his labours took up all his strength ; but, on the contrary, surprising that he had strength enough to do what he did. Seldom free from actual pain, or, at least, discomfort, and never free from harrowing anxiety as to future suffering, he struggled on, doing his duty with the old conscientious thoroughness. He was forced more than once to seek the help of colleagues and friends, always, I need not say, cheerfully given ; but he did all that man could do with a really heroic patience. I have sat with him when he was still in bed from the effects of a painful opera- tion, and in his periods of comparative ease. He was always the same, — cheerful, often even in high spirits ; delighting in talk of all kinds ; keenly interested in all political and social questions, as well as in his more special studies, and yet by no means averse to mere harmless gossip ; while always manifesting a most affectionate zeal on behalf of his personal friends, and of his own and his wife's relations. A man so tormented might have been pardoned for occasional irritability. I will not say that Eobertson never showed such a weakness, but I can say conscien- tiously that I have never known a man in perfect health and com- fort who showed it less. On the very rare occasions in which a little friction occurred between him and some of his acquaint- ances, I was especially struck by his extreme anxiety to say and do nothing which was not absolutely necessary in self-defence, and to guard against being hurried into unfairness by any loss of temper or personal sensibility. I shall never know a juster or fairer-minded man. I always looked forward with pleasure to an interview with him, sure to return on better terms with men and things, with quickened interest in important questions, and with the refreshing sense that I had been in contact with a man of vigorous understanding, and utterly incapable of any mean or unworthy prejudice. " During Robertson's severe trials, his wife's society had been an inestimable support. Of her, I will only say that she was a worthy companion in a heroic life, that she soothed his sorrows, XXIV MEMOIR. shared all his interests, and did all that could be done to secure his happiness. Eecent losses in her family and his own had inflicted wounds, taken with the usual courage. In the early part of this year, a heavier blow was to come. Mrs. Eobertson was pronounced to be suffering from a fatal disease, of which there had, indeed, for some time previously been ominous symptoms. She died on 29th May last, patient and courageous to the end, having in her last illness made every possible arrange- ment for her husband's future life. Eobertson bore the heaviest sorrow that can befall a man in a spirit of quiet heroism, of which, to speak fittingly, one should use the language rather of reverence than of admiration. He had resigned his editorship and his professorship, steps which his wife had seen to be necessary. He did not, however, abandon his intellectual aspira- tions. He spent the summer with his relations, and had sufficient power of reaction to be planning employment for his remaining life. I heard from him not long ago that he intended, upon returning to London, to get to work upon Leibnitz, in whose philosophy he had long taken a special interest. But his constitution was more shattered than he knew. Thei'e was to be no more work for him. A slight chill brought on an illness which was too much for his remnant of strength. He died peacefully and painlessly on 20th September, within four months of his wife. " Eobertson's friends know what he has been to them. They cannot hope fully to communicate the knowledge to others. But it seems to me hardly fitting that such a man should be taken from us without some attempt to put on record their sense of the noble qualities which are lost to the world. What- ever the limits imposed upon him by the circumstances I have mentioned, few men, if any, have done so much in their genera- tion to promote a serious study of Philosophy in England. But those who knew him feel more strongly now the loss of a dear friend. No more true-hearted, affectionate, and modest nature has ever revealed itself to me ; and if anything could raise my estimate of the quiet heroism with which he met overpowering troubles, it would be his apparently utter unconsciousness that he was displaying any unusual qualities in his protracted struggle against the most trying afflictions." PSYCHOLOGY IN PHILOSOPHIC TEACHING.1 THE special question I have chosen for discussion is : What is the meaning to be attached to the phrase, Philosophy of Mind? In the wider sense of the phrase, all philosophy may be called philosophy of mind ; but unless we can some- how limit its meaning, unless there is some part of the whole that is at once central and fundamental, and at the same time suitable for teaching, we are in a bad case. The English teacher of philosophy has not, like the German, a subject divided into well-defined departments, all under- stood to be subordinate to philosophy in general. He cannot range from one to the other without misleading students as to their relation to the whole, but must be severely practical in his choice of subjects. Let us see then if we cannot find some distinct department of inquiry, on the face of it answering to the name of Philosophy of the Mind, and yet so evidently at once fundamental and teach- able, that it has claims on our attention beyond any other department apparently fundamental but not teachable, or really teachable without being fundamental. The importance of Ethics is allowed ; teachable it is beyond question ; but in the Philosophy of the Mind it is not fundamental. ^Esthetics is a subject which, though it has been less elaborated than Ethics, stands on the same 1 Abstract of Introductory Lecture on appointment as Professor of Philosophy of Mind and Logic in University College, London (1866). This Lecture — which is of considerable length— is given in abstract as containing a very clear statement, dating from so early a period, of the position with regard to the peculiar importance of Psychology that Prof. Robertson always consistently maintained. 1 2 PSYCHOLOGY IN PHILOSOPHIC TEACHING. level ; standing only on the same level, it does not fulfil our conditions. Logic, if we were to accept the opinion of some who make it co-ordinate with Ethics and ^Esthetics — the three sciences answering in like manner to the three great departments of Mind, viz., Intellect, Will and' Feeling — is as little fundamental as they. These sciences are all teach- able ; but they are not what we are in search of. They are essentially special developments and applications of something else that is fundamental. Is Metaphysic this something '? Of Metaphysic, there is no definition more serviceable than Aristotle's. Under the name of First Philosophy, Aristotle defines it as the science of the general principles common to all forms of Existence, or, which is the same thing, to the subject-matter of the different special sciences. If such a science existed in an indubitable shape, it could indeed claim to be in a certain sense fundamental and of altogether pre-eminent import- ance. But does a definite Science of Metaphysic exist ? It is true that nearly every great philosopher since Aristotle has had his Metaphysic — observe the expression ; but not one has succeeded in establishing fixed principles univer- sally allowed. Though they have not passed away leaving no trace and accomplishing nothing, yet all the meta- physical systems, as such, have alike come to an end. This is illustrated especially by the history of the ambitious post- Kantian systems in Germany. It is clear that if Metaphysic is ever really to exist in a settled form, it will not come by the way of merely specula- tive construction, as a simple evolution of thought, but in a far less direct and far more laborious way. Without pre- judging the future, then, we may find better employment than trying to persuade ourselves that Metaphysic exists already. Not that the establishment of anything that can be called a Metaphysic must wait upon the completion of the special sciences. At every stage, we must order our knowledge somehow — must encircle it with metaphysical conceptions of some sort. But is a time of widening and deepening special knowledge, both of the world without and of that which concerns us more, the world within, the best time for making metaphysical considerations prominent? PSYCHOLOGY IN PHILOSOPHIC TEACHING. 3 Ought we not now to impress above all the necessity of ex- tending knowledge, and refuse to sacrifice everything to a subject neither easily communicable to beginners nor afford- ing a true starting-point for discovery? The real and natural beginning is a rigorous investigation of the phenomena of mind. If all Philosophy must be essentially Philosophy of the Mind, because it views nothing except in express relation to Thought, the question as to the innermost nature of mental action must surely be taken first. It is Psychology that attempts to answer this question ; and Psychology, which is equivalent to Philosophy of the Mind in a narrow sense, will thus be the most fundamental and representative part of Philosophy, or Philosophy of the Mind, taken at the widest. That this is not a statement made for mere convenience will appear if we turn to history. We shall then find that almost every important philosophical revival after a time of speculative quiescence, and every im- portant philosophical reformation after a time of too highly strained metaphysical dogmatism or unsatisfying scepticism, has been begun by some man who saw the necessity of looking deeper into the mental constitution. The point of view of all modern philosophy from Descartes onward is psychological. It is not English philosophy that has re- mained least true to this conception. And we may find in Germany ardent converts to the cause of scientific psycho- logy as the true point of departure in philosophy. If, as seems now at last likely, the German current of philoso- phical inquiry and the English are about to meet and flow on henceforth in a single channel, it is hardly to the disad- vantage of the English that it has not been spreading itself in futile wanderings, and in vain efforts to water boundless wastes. Psychology then is, and must still be for a long time to i come, the only true point of departure in philosophy for us and for all ; and if it has not been expressly pointed out that it satisfies our other requirement of being eminently teachable, this is because that seemed a work of supereroga- tion. How is Philosophy of the Mind, in its limited sense of Psychology, to be treated? The extremest form which 4 PSYCHOLOGY IN PHILOSOPHIC TEACHING. difference of treatment can assume seems to be found be- tween those who trust to individual introspection only, and take its immediate data as they find them, and those who confine themselves to no single line of observation, but, proclaiming the necessity of analysing back to the begin- nings and elementary conditions of conscious life, think every way good that helps at all to take them there. The Faculty- hypothesis is the proper expression of the first position. It would be unjust, indeed, not to point out that mental introspection, without other aids, has sufficed to lead some, who knew how to use it, to far deeper views*; but, if still further insight is to be gained, we must go not only beyond the traditional doctrine, but beyond the traditional method. If mental science requires only simple observation of the internal kind, what was to hinder observers like Aristotle — a better simple observer modern times do not show — from bringing Psychology to completion ? That physiology in particular, among the objective aids to introspection, gives real psychological insight, may be shown by definite cases. For example, we see the vertical line of a cross longer than the horizontal line when the two lines are really of equal length. The illusion is explicable by the greater exertion required to move the muscles of vertical , than of horizontal motion ; and this explanation is not ' attainable by mere introspection. A more difficult case, where physiology has also proved applicable, is the question of unconscious mental modifications. Again, the distinction between active and passive sensation has already revolu- tionised the question of perception. This distinction was not particularly noted until the time when the modern science of physiology was being founded ; and even if we grant (what is probably not true) that the antithesis could ever have been fully apprehended by the subjective consciousness alone, we are much aided in conceiving it by physiology. To take account of the objective states that run parallel with subjective states is not speculative materialism. Nor does all the difference between the common and the ad- vanced psychology consist in talking about nerves and muscles. If there were time, it could be shown that im- PSYCHOLOGY IN PHILOSOPHIC TEACHING. 5 portant aid is to be got from many other sources ; from comparative psychology, statistics, history, &c. Even then the true difference would not have been given, for it is a difference of general spirit, which shows itself not so much in resorting to any particular species of inquiry, as in a readiness to resort to every kind that can be turned to account. PHILOSOPHY AS A SUBJECT OF STUDY.1 TT having fallen to me on this occasion to offer the few words of general welcome at the beginning of our academic session, I have chosen to speak upon a subject — the Study of Philosophy — which may seem to require some apology. As our plan of education is constituted, and not only here in London, there is no subject included in the round of general liberal study that lies more in the outer confines or is taken up later than philosophy. Very few of you can as yet have begun the study ; of the more advanced there may even be a number who, in pursuance of some more special aims, have determined never to begin ; and those who now appear here for the first time can hardly be expected to feel much concern in a branch of study which they will approach only some years later, if ever they come near it at all. Why, then, for such an audience, select such a subject of discourse? For several reasons. In the first place, the subject being the one in which the speaker is specially interested, he may, to that extent, be likely to speak to greater purpose. If this in general might not be a very safe reason to advance, it may pass here along with a second— that philosophy, however we may put away the teaching of it, is a curious subject, as appealing somehow to all thinking beings, and claiming to say its word about all things ; while, as com- manding interest, it happens to have a curious history, both for itself, and in the particular relation, as a subject of study, in which we are now to consider it. In the third place, if in this particular relation there should turn out occasion for saying something against prevailing views or practice, and 1 The Introductory Lecture at University College, London, October, 1868. — Keprinted, by permission, from the Fortnightly Keview, Decem- ber, 1868. PHILOSOPHY AS A SUBJECT OF STUDY. 7 in favour of different views and a different practice, one could not desire fitter audience than just such an assemblage of young men, all embarked on a course of academic study ; which means that you are open-minded votaries of science, and none of you either too old and stiffened in your ideas, or too young and unconcerned, to be impressed, and perhaps converted, by suggestions put forth in the interest of pure knowledge. These are some reasons, and it would be easy to add others. But I think I may assume that you are all willing enough, in the meantime and until we see, to sink the objection that philosophy lies far away about the end of our college prospectus, out of the path of commoner interest. The fault will then be mine, if at the close the objection is left as one that can still ba urged. It would seem most natural to begin by explaining ex- actly the meaning of philosophy : but I make nothing of leaving that to come out in the course of the remarks. It is not only the foes of philosophy that will be found talking about the difficulty of its definition. Its advocates may very well know that they are fighting for something, and what they are fighting for, although they cannot make themselves comprehended so easily by all, or so precisely by any, as the botanist or the mineralogist. As already hinted, there is simply nothing real or thinkable, and no possible relation among things, that does not somehow come within the philosopher's province ; and this is what no special inquirer can say of his science. We cannot wonder, then, at peculiar difficulties of expression. When it comes to be a question of making charges or suggestions, I am bound to be explicit. Meanwhile, it may be enough to call philosophy the reasoned search for ultimate and most general compre- hension of the universe of things, with conscious regard to the fact of their being thought. Now if history attests anything, it proclaims a search of this kind to be one of the most irrepressible impulses of human nature, as soon as the race anywhere attains a moderate degree of security of existence. It is not, how- ever, this general truth that I want to begin by impressing, but a more special fact, — that philosophy has from of old entered very largely into the educational scheme of the chief 8 PHILOSOPHY AS A SUBJECT OF STUDY. historical peoples, and in this shape has been a great factor in human history. Of necessity we look first to Greece, because it is to the Greek settlers on the coa"st of Asia Minor, who, about 600 years before Christ, began to reason out some general expression for the multiplicity of human experience, that we trace back the whole movement of thought, at least in the Western world. Once begun, how eagerly the move- ment was sustained by different sections of the Hellenic race is a remarkable story, even before we can clearly note at Athens, less than two centuries later, its first large edu- cational result. About the Sophists we all have heard, and about Socrates, whom some call the greatest of them, and others the founder of a truer teaching upon the overthrow of theirs. For our present purpose it is enough that in the fore- most human culture of that time questions of philosophy — reasonings about the general frame of things and all the highest concerns of humanity — made so great a part, that the youth of the small city then at the head of the race could support a large band of philosophical instructors, and helped to excite to a life of strange questioning and critical activity one man with whom the human mind awoke to a new apprehension of the meaning of science or true knowledge. And this was but the first result. For, from that time, as the history of Greek literature was mainly the history of Greek philosophy, of efforts unceasingly carried on, amid political revolutions and national decay, to compass the nature and reason of things, to discover the rational rule of life, and unlock the secret of human destiny, so all highest instruction was had in philosophic schools. Nor must we think thus only of Greeks. The ancient pagan world, enduring some four or five centuries into the Christian era, never knew the national rivalry in science and philosophy so familiar to us ; and though Boman dominion might cover all, and Latins contest the palm with Greeks in poetry, oratory, and history, the philosophical thought about man and the universe was always in substance Hellenic. To the last the ancients had but two great centres of science and learning, or, as we should say, universities ; and they were the Hellenic cities of Athens and Alexandria. When we PHILOSOPHY AS A SUBJECT OF STUDY. 9 see, then, at Athens, the chair of Plato filled by an unbroken line of teachers for some 800 years, and observe the struggle between Paganism and Christianity protracted at Alex- andria by the desperate efforts of Neo-Platonist professors to retain hold of the minds of youth, with a doctrine com- bining the mysticism of Plato and the width and demon- strative force of Aristotle, we could not have more striking evidence of the place and power of philosophy in the ancient instruction. Upon the triumph of the Church, coinciding with the great inroads of the barbarians, the centuries of darkness and confusion followed, and when the light of philosophy and science went up in the world again, it was first in the Arab dominion stretching from Bagdad to Cordova. But in Christendom, also, no sooner were monastic schools planted during Charlemagne's brief triumph over European disorder, than philosophy resumed her ancient place at the head of instruction. Alcuin was sent for from these islands, where the darkness had never been so complete, to direct the -new intellectual movement ; and in the next century, the ninth, another philosopher, John Scotus Erigena, Irish or Scotch by birth, struck at Paris the first note of that famous system of Scholasticism which, after another century or more of blank confusion, engaged all the intellect of Europe until the fifteenth, and struggled for mastery over the human mind far into the modern period. By nature the very opposite of an unfettered and disinter- ested intellectual search for truth, scholasticism, or Church- philosophy, did yet include an element of independent thinking for which it has seldom got credit ; and incorporat- ing itself in a remarkable organisation of instruction and free interchange of thought, it was for a long time in a very real sense a philosophical liberal education. And, for one thing, it is by no means clear that in so greatly extending the scholastic horizon of thought and knowledge, we have been as careful as the schoolmen were about the discipline that gives the power of sweeping it. The sixteenth century ushered in a new era. It was not, as some say, that positive science then of a sudden sprang into life ; for, although the chief scientific discoveries 10 PHILOSOPHY AS A SUBJECT OF STUDY. began to date from about that time, the mistake is as great to suppose that men did not scientifically observe, experi- ment, and reason before, as that they never have used wrong methods or landed in unscientific conclusions since. Nor was it because, qwing to a hundred social and political causes, the revival of letters took place, enriching Europe with the treasures of ancient literature, and overpowering the scholastic mind with a first true notion of what the Greeks had achieved in philosophy. It was rather that men had outgrown — very slowly, but still outgrown — the scholastic conceptions, and could no longer be held by so narrow an idea of the universal order, nor satisfied with such a notion of the human lot. So, except for the natural revulsion in a number of miuds against everything — even to the name of philosophy — associable with the cast-off system, it was an ardent desire for a new settlement of all highest questions rather than any disposition to ignore them, that characterised the transition to our modern .period. The men who at last, after a time of fermentation, opened the paths of modern activity — Bacon, Descartes,, and even Galileo — had all the large grasp, and each in his own way conceived the scientific task with the compre- hensiveness and peculiar insight that mark the philosopher. So far as their influence prevailed in the seventeenth century — Descartes' in particular — against Scholasticism, which died hard in its own universities, there was no decline in the philosophic character of liberal instruc- tion. I might carry this review further, but I am content to have merely brought before your minds the connexion of the study of philosophy with the great stages of human history, if thus there may appear some reason for looking more closely to see what place it holds in the education of the present day, when public instruction has become the foremost social question for all. First, for other countries, we may glance at France and Germany. In France, a course of philosophy, meaning logic and psychology, enters, nominally at least, into the secondary, or general liberal education of the lycees or public schools, and there is provision for prosecuting the subject PHILOSOPHY AS A SUBJECT OF STUDY. 11 specially, in the superior, or faculty instruction. In Germany, the study of late, practically, has vanished from the general or gymnasial course, except as it has been prominently brought forward again in the new liberal system of Austria ; at the universities it retains the place it never ceased to hold, and now for a century has held in such a way as more than anything else to have procured for them their unique reputation, and for the country its place at the head of European thought. Thus a faint recognition of philosophy as a subject for all, more especially in France, and a striking acknowledgment of the importance of its special cultivation by a smaller number, especially in Germany, — this is what we observe in the chief Continental countries where the educational system has been recast for modern wants, on the definite principle of separating general and special training, and completely organising both. In our own country there has been no general movement of reorganisation, nor, to aid us in appreciating the exact position of the subject, is there a uniformity of system. Still, amid the great difference of educational resources, appetite and results, from one part of the island to another, our teaching universities happened to agree in being first of all places of general education, and not seats of high special instruction like the chief universities abroad ; special study with us, except in three professional departments, which, in a more or less perfunctory way, are provided with instruction, being left to private work, under a spur of honours examinations, or some other kind of reward. Now, evidently, one consequence of this for the study of philo- sophy must be that it is nowhere, unless accidentally, carried very far. But there will also be this other conse- quence, that where the subject is seriously taught at all, it will affect a large number, and, as a university-subject, probably affect them more deeply than if it were taught at school. Both results are precisely what we find appearing in the Scotch universities — institutions that have long performed with credit the task of imbuing a very large proportion of the youth of the country with a liberal instruction, that has 12 PHILOSOPHY AS A SUBJECT OF STUDY. been found an admirable preparation for practical life, and a very good general basis for the few who have gone else- where to make special studies. Every one of the many Scotchmen completing a liberal education at home attends a long and serious course of lectures on logic, and another on ethical or metaphysical philosophy. I do not know another system of general education that either enjoins so much of high discipline, or manages to make it so effective. Germany, if she gets far more out of some at the univer- sities— and let Scotland look to that — certainly gets nothing like it out of the many, either at university or gymnasium. And the system, on its strong side, has effects which may be traced not obscurely in British literature and science for the last 150 years. The old English universities cannot be said, like the Scotch, to save their reputation by spreading wide the philosophical instruction which they do not carry far. At Oxford, the rival of Paris in the great days of scholasticism, and Cambridge, the seat of a school of thought as late as the seventeenth century, the study of philosophy, from a multitude of causes, sank to the lowest point in the eigh- teenth, from which it is still only in process of revival. A.S things stand, in discharge of their function of places of general education, both admit philosophical study, but it is not exacted as in Scotland. Higher study they encourage, the one by giving it a prominent place in the honours and fellowship examinations, the other by a special examination indeed, but one which hitherto has conferred barren honours in a region where academic honours are anything but barren. It would be wrong, nevertheless, not to acknowledge the ardour with which some have worked for the restoration of philosophy to a more worthy place in Oxford and Cam- bridge ; and for this, as for other things, the future is full of hope. I come now to ourselves in London, with our instruction and examination of purely modern origin, and constituted independently of each other. The examination-system of the University is particularly worthy of notice, being the most varied and comprehensive that exists, and specially calculated for present wants. The recognition of philosophy PHILOSOPHY AS A SUBJECT OF STUDY. 13 is very remarkable. For the B.A., or common degree in the liberal arts, as much knowledge is demanded as at the Scotch universities, and the higher degree of M.A. can be taken in philosophy, along with political economy, as a special subject. From a system of examination nothing more could be sought, either in the way of making the study general amongst men of liberal training, or of en- couraging a few to go deeper. But the action of the univer- sity does not stop here. It grants also degrees in science, upon the guarantee of the matriculation test for general knowledge ; and here, while requiring for the lower degree as much philosophy as for the B.A., offers the higher scientific distinction for special proficiency in the subject under the name' of mental science. Again, nothing more could be desired, either for imbuing scientific men generally (for reasons we may have occasion to see) with a philosophic spirit, or for stirring up carefully trained scientific minds to the deeper investigation of philosophical questions, which too often, it cannot be denied, have been made the sport of poetic fancy or been taken in hand by those who were interested in a certain solution of them. Nor does even this complete the account of the recognition of philosophy. The University of London stands alone in requiring of medical graduates who aspire to the highest professional status, that they shall not be ignorant of the laws of the human mind and of scientific method, the neglect of which has been fatally avenged upon the progress of medicine ; anticipating here a reform of medical education that cannot be far distant. It was not too much to speak of a very signal recognition of philosophy ; and taking the university only for what it professes to be, one might say further, that there is in all this a very felicitous blending of ancient prescience with modern experience. But if London stands thus distinguished in philosophical examination, it is only a reason the more for looking closely to the philosophical instruction ; which brings us home at last, because University College, once the London Univer- sity, claims still to rank first among the instructing bodies. And in support of the claim there could hardly be better proof than the fact that, beyond any other, this college has 14 PHILOSOPHY AS A SUBJECT OF STUDY. maintained in her curriculum the teaching of philosophy. The fact admits of even stronger statement. As the present University is more the daughter than the mother of our College, and certainly owes its breadth of spirit to the same movement of thought and even the very minds that begot us, we may consider that a great part of what is best in its constitution is not so much a something for us to work up to, as a recognition and expansion of principles that first were rooted here ; and notably in this matter of philosophy. For our founders, at a time when the philosophical tradition had nearly died out at Oxford and Cambridge, and when, by a curious irony, they could not be more distinguished from those who sat in the seats of the schoolmen than in setting up a chair of philosophy to take an 'effective part in general education, instituted in this place the first chair of the kind in England. Still, with reference to this chair so intelligently conceived, one hardly knows, after the changes and experience of thirty years, how to speak. The large scheme of the University cannot be said to be very well met by the energies of a single instructor, especially in its higher developments. On the other hand, the apathy of our people for high culture, which has hitherto sadly prevailed against the generous efforts of the founders and guardians of Uni- versity College upon all lines, has shown itself quite specially upon this, to the extent of leaving hardly used the little teaching-power provided. It is not only a curious, but a serious thing. Berlin gives employment to some ten publicly-recognised teachers of philosophy. London, even after the singularly striking testimony borne by the new University to the general and special value of the subject, finds one rather superfluous.1 1 Mr. Mahaffy, writing in the last number of the London Student about the Dublin University, complains, with great justice, that little account is taken in England of its progress, and even its very existence. I am the more sorry that these observations of mine come under this re- proach, because, upon inquiry, it turns out that no place of education more deserved notice for its recognition of philosophy. The subject (only it seerns to be made rather much an affair of book -work) is both firmly rooted in the ordinary course, and placed fairly on the line for academic distinctions. The Irish Queen's University also merited a passing notice for exacting attendance on a philosophical course. Having had occasion to mention the last number of the London Student, PHILOSOPHY AS A SUBJECT OF STUDY. 15 Upon this review, hurried and partial as it is, I think we may say that, while philosophy clearly has lost its old predominance in liberal instruction from the days when a change of speculative theory meant an educational revolution, its varying position from country to country, and its more or less unsatisfactory position in all, betoken great disagree- ment and uncertainty about its value as a subject of study! Germany carries philosophy much the furthest, but one must go to Germany to hear its general utility scouted with thorough vigour. Scotland spreads it well, but has little training for special aptitude. England, at the old university seats, is only recovering from the habit of total neglect, or in London has not got much beyond the conception of a brave ideal. Under these circumstances, let me proceed to explain how, as I conceive, philosophy, though it stands no longer where it stood, still has claims to a place in modern education. For the declension of philosophical study, reasons are not far to seek. To take the smaller first, it is plain that, as the world advances in culture, a literary education must tend to engage a larger number and increasingly to engross the mind. This was seen in the later ages of antiquity, when they became weighted with a great literature. It is to be seen still more since the Revival of Letters, when the nations of modern Europe got sudden possession of the literary relics of the classical peoples, and after a flush of bewildered admiration, began to pile up fine creations of their own. In the ancient world, philosophy was more powerful as an intellectual regimen before the days of wide- spread literary culture ; and unless modern civilisation is moving onward to some new catastrophe, mankind can hardly again be seen in the position of the schoolmen, hugging for .centuries a few philosophical ideas saved from a periodical started a few months ago, under the able guidance of Prof. 8eeley and others, to work for the organisation of the higher in- struction in London, I think it pertinent to add that this (October) number was the last in every sense. Nothing is, of course, more natural than the early death of an English educational journal ; but the fate of this greatly dejects some who were simple enough to fancy that at last the time had come when such an one might live. 16 PHILOSOPHY AS A SUBJECT OF STUDY. the flood, until the re-awakening of fancy and literary taste. But this is not much against the influence of philosophy. If the paths of literature, when they open, entice multitudes to wander down them, the world never contains fewer difficulties to solve or tends any the more to cease from breaking in upon the mind's repose. The search for largest truth, which is philosophy, cannot slacken with the growth of literary culture and general refinement, unless the race is falling back ; and if in modern days the old philosophical highway is trodden by rarer feet, the cause is more probably that other roads to truth have been opened. You may easily guess that I am thinking of the multifarious lines of modern science. Now, however exclusively the sciences may be under- stood, or in whatever narrow sense the one word 'Science, as arrogated for the multitude of modern positive inquiries (but it means simply knowledge), is opposed to all or any- thing that has passed under the name of Philosophy, you shall hear no jealous complaint from me. The man must be blind indeed, who does not see that sentence has long gone forth against ancient preconceptions of nature, and that the special sciences of modern times have availed to give insight into things that baffled too forward minds in early days. Has something that men do not call philosophy come at truth, or say truths, which philosophy upon a different line tried hard, but failed to reach? I wonder what philosopher, that is to say, what deepest and widest truth-seeker, should not there find cause for joy. There is truth of fact, and truth of manner, and he will always deserve best, who seeks out anything in the truer way. Since there is a truer way than once was mainly followed, of arriving at some knowledge of the vast complex of nature, in the following of it there lies not only an ex- planation of the comparative decline of philosophy in the modern world, but, one can even say, a philosophical justi- fication. Ancient, scholastic, even seventeenth-century philosophy, we are not to forget, sought to be physical science as well. The philosopher Aristotle was, in the strictest sense, the great scientific authority for ages, until PHILOSOPHY AS A SUBJECT OF STUDY. 17 he was dethroned by the philosopher Descartes. Both were, like Locke, Newton, and Harvey, rolled into one ; except that Locke's philosophy was in some respects better, and Newton's physics and Harvey's physiology very much better. The days are gone of a universal oracle like Aristotle ; a new Thomas, who should dispense to hungry youth all knowledge, human and divine, would be the Angelic Doctor indeed. When one thinks with what accumulated labour of generations, with what painful concentration upon details, the conceptions that are now set before the scientific student in any known department of nature have been spelled out, one need hardly wonder at modern impatience of philosophy, which, for the external world at least, used to mean crude generalising, rash deduction, and self-complacent projection of human fancies and likings. But was there nothing, then, in that ancient habit of thought, which, even at the expense of our objective sciences, gave, in what was called philosophy, a unity to human knowledge that is strange to a modern ear ? Is it enough for men — for thinking beings — to burrow, like many, all their days in holes and corners of the universe, without trying, or conceiving how they might try, in thought to take in the whole, — to be moved to ecstasy in counting the spots upon a butterfly's wing, or the facets of its eye, and to care nothing for the questions about human knowledge and human nature underlying all? We agree to protest against so-called philosophic disdain of things mean, or facts precise or exact ; but is it everything to ticket and label all round, or is it the highest to have even weighed the planets and measured the interspaces of the stars ? It is not necessary to go to those who are directly in- terested to find the negative answer. The labours of a man like Comte, steeped in objective science, but convinced that all this random exploring of the last centuries must be abandoned for a course of wisely-directed intellectual effort, in view of the .highest human ends, yield it : it is yielded recently in more than one striking statement of the bounds set for physical inquiry and avowal of a great region -of human interest lying beyond. What, if we shall find here 2 18 PHILOSOPHY AS A SUBJECT OF STUDY. only a recurrence, of a partial kind, to the old and neglected idea of philosophy ? Let us suppose a number of men, of wide scientific attainments, to devote themselves not to carrying further specific lines of investigation, but to knitting up the multifarious threads of inquiry, to weighing their relative importance for humanity, and evolving out of each lessons of method for the benefit of the rest. Such men — Comte himself is an example — could not, or at all events would not, be called men of science, but would do a greater work, in some respects a higher, because a rarer work, than detail inquiry, and would fairly claim to be called philo- sophical. Suppose another class of men, less concerned about external things than the shifting scene of human thoughts and feelings, to undertake the delicate task of gaining some intelligent insight into this strangest of complications ; with this view, to fasten upon all outer manifestations of consciousness, even more as helps to conception than as facts, and, both here and in the far greater number of cases where such help can only be vaguely had, by analytic reflexion to labour at reducing the acquired and the complex to the rudimentary and the simple. Such men might not (except by Comte) be denied, as psychologists, the name of men of science ; but, as facing the multitude of difficult questions regarding human nature which, though not unapproachable from the side of the physical sciences, can never by men be placed on the same level with physical questions, their work also gets the name of philosophy. Now, there always have been some in the number of tradi- tional philosophers attempting, as far as their light went, one or both of these functions ; and the functions being declared necessary in quarters where there can be no sus- picion of interested feeling, there is already in this a plea for philosophy beside the sciences. But now suppose still another class of men — though it best might be our second class, the psychologists — to be deeply impressed with a consideration which there is no reason for not ignoring in practical life, but which is also so habitually ignored elsewhere as rarely to enter the head even of men of science — the consideration, namely, that this great world after all is, and can be, only as it is mentally PHILOSOPHY AS A SUBJECT OP STUDY. 19 perceived or conceived, and that it is as idle for men to try to get out of the mental circle to an existence that is not thought or somehow experienced, as to overleap their shadows. Strange as this may appear to some of you, it is anything but a whim or fancy ; and it has undoubtedly been the profoundest conviction of many of the greatest minds. Does it not follow that in carefully studying all that we are conscious of — not, with the physical inquirer, as things and facts related to each other in an external world, but as objects of our thinking — any results we arrive at will have a permanent and universal validity, whatever be the specific data started from — will be true of all things, if true of thinking, and will be a truth' not otherwise to be attained ? The scorn that is so freely poured upon metaphysical philo- sophers, without a faintest thought of this, is a very cheap scorn. If we will think of it, we shall understand very dif- ferently the efforts of so many searching intellects from that early Greek time till now ; and yet without prejudice — perhaps even in truest devotion — to the cause of modern science. Why did good physical science begin so much later in the world, and, such as they had it, count in Plato and Aristotle for so much less, than philosophy? Not, surely, because the Greek thinkers were wanting in the requisite intellectual force, or because their philosophy was play ; but rather because their philosophical thinking sprang more directly from, and was a more pressing need of, their mental nature. Why is their philosophy to this day a power in the world, and why does it worthily engage the labours of the most vigorous minds, but because it includes wisdom and far-reaching stretches of thought, which some may refuse to call truths, but which are worth more, and are more needed, than bushels of the facts to which the name is given ? Why is most of their physical science a mere antiquarian curiosity, or good for little but to point a scien- tific moral? Because they failed to see how far mere thinking can go, how sober it ought ever to be ; because they had not learned that if it will try to cope with the infinite complexity of nature, it must start from a very firm ground of experience, and never be weary of alighting again to test and verify its conclusions. 20 PHILOSOPHY AS A SUBJECT OF STUDY. There is a difference between not having a right to be, and straying in the attempt to compass too much. Philo- sophy strayed thus ; and modern physical science, upon a hundred lines, had a revenge to take. But now that, by an ardour in pursuit beyond all praise, and a harvest of results, intellectual as well as material, scientific inquirers have brought things to this pass, that nothing is better estab- lished than the way of the sciences, nothing more certain than their future, is it not time to drop an opposition that is full of danger ? If the philosopher erred when he fancied that from the height of his swift thinking he could take in the world by glances, the physical inquirer, in seeking laboriously to make good the error, is not therefore safe. He works with assumptions, of which he can render no sufficient account ; and because he cannot, he often works wastefully. He works without having reflected upon human ends ; and because he has not, he often works uselessly. He works by rules which he does not compre- hend ; and because he does not, he often works astray. Or, if he can render intelligent account of his Assumptions, if he has reflected upon human ends, if he does apprehend the true force of his rules, well for him ; but then he is to that extent a philosopher. When, in some distant and happy future, all men of science have become philosophic, and are as remarkable for depth of insight and width of view as now for patient and devoted search, it will be time enough to ask whether philosophy has not wholly passed into positive knowledge, as positive knowledge will then be conceived. Meanwhile, there is so much sifting and criticism of scientific assumptions to be done, and so much ordering and estimating of scientific results — there is such need of anticipative thought for holding our experiences together, and of reflective consideration of our mental life to settle how and where we stand, that the last thing we can afford to do without is a philosophy. And, besides, it is, after all, not a question of philosophy or no philosophy, but only of good or bad : for, as Aristotle said, men must philosophise. You will observe, I here put the case merely upon the ground of a necessary relation between philosophy and PHILOSOPHY AS A SUBJECT OF STUDY. 21 every kind of special inquiry ; not, however, that I think it cannot be argued upon a directer issue. It is not asking very much of the mind that it should labour to settle the questions it can raise, or, rather, cannot repress ; and if, as many are rather suspiciously eager to suggest, the questions are not to -be settled, we surely have a right to know the reason why. We cannot go on living, still less thinking, without stumbling upon numberless difficulties, leaching even to our very life and thought; and although, 110 doubt, some may choose for themselves not to face them, there are others who must be allowed to choose 'differently. Nor is mere settlement of questions everything ; as the world goes, there is virtue for every generation in the raising of some : and when comparisons are drawn to the disadvantage of metaphysical philosophy from the settle- ment of physical questions, it may be enough, without retorting upon doubtful passages in the progress, or doubtful points in the present state, of the sciences, to reply that- it very much depends upon the kind of questions and the kind of settlement. On the whole, I venture to submit that it never was of greater importance than now to recognise and have taught, under the name of philosophy, the best possible knowledge regarding the human mind ; which will range over more than you would suppose, but will include at least this — an account of the growth and mature mani- festations of mind in the individual, or psychology ; the same for the race, which is the history of speculation ; and in connexion with this or separately, the discussion of all largest scientific ideas, or Metaphysics ; Logic, or the general science of proof and discovery of truth ; andiEthics, or the science of human conduct. To this last, leading on to so much else, I have only distantly, alluded before, though the whole case might be rested upon it'; the others are an intellectual regimen, without which there can be no highest culture for men, and no true idea either of human power or of human impotence. But if philosophy in this sense is still to be taught, it is plain, in the first place, that there must be opportunities for making it a subject of special study, were it only to train a competent body of teachers. Here, in London, this is' one 2'2 PHILOSOPHY AS A SUBJECT OF STUDY. of the chief things we have to think of; the more, as already our instruction lags behind the admirable system of examina- tion I exhibited to you. But the matter has a wider aspect. Now that our people are being shaken from their intellectual trance, if London should, as with its resources it might, be- come the centre of the world's learning and science, greater would be the need that human thought should here, in philo- sophy, labour hardest to grasp and guide the whole. For all our restlessness, we are taunted with being a narrow- visioned people ; and we cannot deny even to ourselves that our achievements are not won without a waste of power, moral, intellectual, and material, enough to make the fortune of many a more frugal, or better-instructed race. The taunt, with our past in view, cannot have more than a passing truth. As for the waste of power, that is sheer senselessness, and must be stopped. Let our instruction be made the best, as it still easily may ; let us put aside this late-born horror of theory, and be less afraid of thought for having sometimes strayed, assured that no hard thinking is ever quite lost. Our love of facts and devotion to practical results will not suffer for being so enlightened ; while all the experience we have heaped up, and must ever continue laboriously to bring together, may perhaps yield an intellectual satisfaction to which there are few among us not strangers. But it is as a subject of general study that I am more con- cerned now to recommend philosophy, in view of our actual teaching-resources, and to an audience like the present. The chair of philosophy and logic in this college was, as I said, founded to take part in the work of general, liberal instruction, and singly cannot, except very feebly, overtake special functions of the kind now hinted at. Before an audience, too, composed of students still at the stage of general training, I may best close my remarks by showing, as far as time will permit, the advantages of philosophy as a general preparation for the chief special pursuits that in the end must engage the liberally instructed. I do not stop to give reasons for the selection ; but you will hardly call it unfair, if we confine ourselves to the scholar, the lawyer, the man of science, and the physician. The scholar is a somewhat indefinite title, and may mean PHILOSOPHY AS A SUBJECT OF STUDY. '23 little or much. It means least when it designates the scholarly man of traditional English growth, who, being anything or nothing besides, does not seek in his scholarship more than a means of fine recreation or a standard of liter- ary taste. Him we may pass by. It means something very serious, as suggesting a teacher of youth ; which it does with a frequency in proportion to the prominence given to lan- guage, and particularly the classical tongues, in mental training. Putting here aside the great educational question now pending between languages and sciences, I will only say that, more especially if instruction is to be mainly linguistic and literary, the teacher will do well to have been led by psychological study to reflect upon the subject of education, and to conceive that at least the manner of instructing dare not be unscientific. The scholar may, however, be more. With the measure of insight that has fallen to him, he may set himself to explore all mental growths and creations of the race in language, literature, art, polity, religion. He may put together all his thought and research in a history of some people, or period, or phase of mental effort ; perhaps calling up the past in order to win from it moral and politi- cal lessons for his own time, more impressive than any ab- stract teaching. From words or myths he may try to distil subtle truths about pre-historic races. You may call this science : it is, in any case, putting erudition to its highest uses. Now one can call up such and such a scholar or historian, in whom conscientiousness, labour and rhetorical gifts are nullified by an incapacity to appreciate the weight of conflicting evidence, to comprehend the springs of human action, to conceive of human destiny with large vision, for mere want of logical training and familiarity with the analy- sis of the psychologist and the wide conceptions of the philo- sopher. One can think of such and such another, in the present and past, whose insight and free range of thought stand first among their high qualities, and by themselves would be ascribed to the influence of philosophic studies. We have had great scholars in England at different times. Let me put a question. How comes it that of the im- mense number of English students, who were classical or nothing, trained in the last seventy or eighty years, so few 24 PHILOSOPHY AS A SUBJECT OF STUDY. have contributed to the remarkable philological achieve- ments of this century ? Till you bring a more likely ex- planation, I should ascribe it to the long eclipse of philosophy and the philosophical spirit at the old universities. The pursuit of law, which some of you will follow, is a very striking case for remarking the need and advantage of a general philosophical training. Nothing can be more ap- parent than the connexion of positive law through juris- prudence with morals and psychology. Nor is there anything more, or at least that might become more, commonplace, than the fact of the pointed application of syllogistic theory in legal pleadings and decisions, especially under a system of judge-made law like ours. But our own law, in its present condition, is also quite otherwise an object of interest to a philosophically trained mind. Sharing with other systems a number of hazy notions regarding law of nature and the like, which, if generated by a lax, can be cleared up only by a rigid, philosophy, it continues, unlike others, to be twisted by haphazard growth into monstrosity. The simplest rules of logical definition, which, if in other matters, men did not observe, or try to observe, there never could be science or knowledge, our lawyers alone seem to claim the right to disregard. They have gone on through centuries referring, with a fatal ingenuity, the multitude of new cases to an inadequate stock of original conceptions loose in themselves ; and the consequence is, that a good definition of a legal term is now hardly to be found. There is no work more pressing at the present day, or more fitted to fire ambition, than the scientific reconstruction of English law ; and the student, eager to aid, will not find better training than a course of philosophical instruction, impressing the conditions of all rigorous thinking, and accus- toming the mind to move with steadiness among largest conceptions. Upon the relation of philosophy to the sciences I have already spoken at length, and touch the subject here again only to say a word for theoretical science as a professional pursuit. It is a feature of British science that it is left in great measure to the spare energies and chance leisure of busy practical men ; much to whose credit it undoubtedly PHILOSOPHY AS A SUBJECT OF STUDY. '25 is that so many are found willing to undergo labour of the kind. But, either on a comparison of results, or upon the least reflexion, it is impossible to regard such a state of things as satisfactory ; and at no point do we suffer a greater waste of power. To stop the waste, indeed, is difficult, until by developing public instruction we provide, us in some other countries, a large number of modest places to be held on the simple and effective condition of requiring for scientific work done merely a free and open exposition of it. It is not, however, that there is a want of actual resources, if one might here venture to suggest what a power the old universities have long had of stemming the evil, by affixing such a condition to only a few fellowships, diverted from being extravagant prizes for past under- graduate work. Suppose the thing had been done — rigidly done — from the days of Newton : where might we not have beeiL now? The sooner something is still done, there or here, the better for our national reputation ; and in propor- tion as we couple a philosophical culture with the special training of the scientific class, a point in which it is still open to us to surpass other nations, the better will it be for •our science — and our philosophy. The medical profession, concerning which I engaged to say a last word in the present connexion, has specially distinguished itself in the way just mentioned of working at pure science amid laborious practical duties ; so that after all the name of physician is not greatly misapplied. Nevertheless it is asserted, and not denied, that our medical men, as a class, come greatly short in the matter of preliminary general training, scientific, and even literary. One can urge the charge altogether with less hesitation because a change for the better has already set in ; and, in An assembly like this, there is least of all need to cast about for a mild expression of it, when by their presence here the future medical students of your number take the best means of eluding the reproach. Even the practice of such, however, will bear to be enlightened, to say nothing more •of the immense stride the others have to take ; .and en- lightened it may be by including in their general studies here the philosophical discipline offered in our course of 20 PHILOSOPHY AS A SUBJECT OF STUDY. instruction. It is little short of mockery to ask, what can be the use of such a discipline to a medical man ? When existence is hanging by a thread, or is endangered by a. subtle malady, whose secret is betrayed by few outward symptoms and cannot be approached by a rough experience, is a man to resign himself to one who has not the faintest idea of what is good evidence, and never has bestowed a single serious thought upon the mental moods that are more than half our human life ? If it were true that logic and psychology will not give much help, the case is still one where people can ill afford to reject a very little ; and what logic and psychology can do for a mind that comes schooled in them to the discharge of functions the most delicate and momentous, those who neglect them are not the be'st able to say. You who are so fortunate- as not to- have been thrown prematurely amid the distracting variety of medical studies, which is the only good excuse the others can offer for the neglect, are those of whom it may be asked that they should give the discipline a fair trial. The present experience is unfortunately not great, either at home or abroad — this, indeed, is the very point com- plained of; but, as far as it goes, it justifies me in saying that you are little likely in after days to regret any trouble less. It has been assumed in these remarks that philosophical knowledge is not only good to have, but is best got from a course of systematic instruction. I must not close without a word about that assumption. When an unpopular subject has its claims thus pleaded, there will be many ready enough to concede them, .because it -can 'always be said .the knowledge is of a kind that may be trusted to come of itself or with other knowledge ; and logic in particular, as it is the philosophical discipline with the most obvious and urgent claims, is perpetually being shelved in this very plausible and convenient fashion. The subterfuge is a little too transparent ; it is, besides, not very safe, for logic is not the only abstract doctrine that can suffer. Whatever may be known, or has to be practised, is better for being ex- plicitly set forth; in that way far more can be known, and bad practice is rendered more difficult. And this is neither PHILOSOPHY AS A SUBJECT OF STUDY. 27 to deny, what is no doubt a fact, that some heads need very little formal instruction, nor is it to assert that everything that can be explicitly set forth ought to be made a part of general education. But there are few for whom Philosophy has no lessons, and I should hope it will now appear to you a subject of study with very peculiar claims upon all. THE ENGLISH MIND.1 AFTEE expounding, by the mouth of a feigned Oxford student, one of the most characteristic products of English thought in this century — the logical system of John Stuart Mill — M. Taine proceeds, in his brilliant French way, thus to catch up his youthful champion of ' English Positivism,' as he calls it : — " An abyss of chance and an abyss of ignorance. The view is gloomy : no matter, if it is true. At all events, this theory of science is the theory of English science. Seldom, I grant you, has a thinker better summed up in his doctrine the practice of his country ; seldom has a man better represented by his negations and his discoveries the bounds and the reach of his race. The processes of which this thinker makes up science are those in which you surpass all others, and the processes which he shuts out of science are those in which you come short more than any. He describes the English mind when he thinks he is describing the human mind. There lies his glory, but there also lies his weakness. In your idea of knowledge there is a gap which, being constantly added to itself, becomes at last this yawning gulf of chance from whose depth, according to him, things come forth, and this gulf of ignorance on whose brink, according to him, our knowledge must halt. And see what comes of it. By cutting off from science the knowledge of first causes, that is to say, of things divine, you drive a man to become sceptical, positive, utilitarian, if his head is hard, or mystical, fanatical, methodistical, if he has a lively imagination. In this great unknown void which you set beyond our little world, the hot-headed or the melancholy can lodge -all their dreams; and the men of cool judgment, 1 A Lecture delivered at the Russell Institute in April, 1871. THE ENGLISH MIND. 2£ in despair of gaining any footing there, have nothing left them but to fall back upon the search for practical receipts that may better our condition. It seerns to me that oftenest the two dispositions meet in the same English head. The religious spirit and the positive spirit live there side by side and apart. That makes an odd mixture, and I confess I like better the way in which the Germans have reconciled faith and science." It is cleverly said — too cleverly, for if in all generalities there is apt to lurk a mental snare, there is especial danger in the attempt to dash off with points of this sort the character of the manifold thinking of an old historic people. In phrases less sparkling, but of almost identical import, one of those very Germans has sought to describe the quality of French thought, and the names of many Frenchmen, Pascal for one, rise at the words. Nor, again, have the Germans succeeded so very perfectly at the task of reconciliation — certainly, not Kant, the greatest of them all. And yet it must be granted that those telling sentences embody an opinion of the English mind that does prevail abroad, and sometimes finds vent at home. As represented by our intellectual leaders, we pass for being gifted with much practical sense, with much insight into the relation of means to ends or interest in the sort of knowledge that gives immediate power over things; but are declared to be singularly wanting in elevation of thought or passion for the merely true, and to be utterly impatient alike of far-reaching principles and of rigorously drawn-out conclusions. The Germans deny us their ineffable Geist ; the French deny us their inexorable logic. It is freely allowed that we have done considerable things in the positive investigation of nature or of external human relations, like those that come into political economy. It is not denied that somehow, with all our devotion to utilitarian knowledge, we have managed to preserve a vigour and freshness of imagination, whence has sprung a poetical literature as rich and lofty as any the world has seen ; though it is some consolation to our critics to think that they alone can appreciate its worth. What is denied, as here by M. Taine in the earlier part of his oracular utterance, is that we are a people of ideas, to whom simple W THE ENGLISH MIND. insight is the first and highest. Or it is sometimes more bluntly put, that we have no philosophy. The charge is not, indeed, one of old date. Time was, not very long ago, when the character of an intellectually forward race was the iast that would have been withheld from us. It would not have been gainsaid by the French who, for near a century, gloried in following upon the track of Locke and Newton. Neither was it grudged by the Germans, who about the same time were not only cultivating their taste upon English models before entering upon their own great era of literary creation, but received also, though some of their descendants have forgotten the debt, their most effective impulse towards philosophic thought from Locke again and from Hume. No higher than to the time of influence of the new German philosophy, begun by Kant less than a century ago, can be traced the origin of the opinion that we fall short as a people in philosophical apprehension ; and of course the weight of the opinion must depend on the credit maintained by that philosophy. Now it is a fact that in this present generation the rising thinkers, both German and French, tend more and more to come back to the intellectual point of view so scornfully decried as English by their fathers. But let that pass. Enough, for the present, that the charge as currently urged is seen to be not over-deeply supported. What force there is or is not in it, we may make out upon a line of inquiry of our own — a line that shall be mainly historical nor that of short reach. Let it however first be understood that by English is here meant in the broadest sense British, inclusive of Irish and Scotch. The chief effect of the extension, so far as regards the modern period of history, is to bring into the reckoning a number of thinkers that have given fame to the northern part of the island in the last 150 years ; but to exclude the sister-country would, within the same time, throw out no less a figure than Bishop Berkeley, who, though of English extraction, was in Ireland bom and bred. It may indeed seem questionable to include philosophers hailing from beyond the Tweed,.; for did not his majesty King -George III., in the interest of English common-sense, for- THE ENGLISH MIND. 31 swear and renounce ' Scotch Metaphysics ' ? or, if that be not decisive, has not Mr. Buckle shown that all Scotsmen reason on a method the exact opposite of that which has become almost identified with the English name — and everybody knows that in philosophy the method is every- thing? Notwithstanding, I take leave to submit that there is no opposition between the English and Scotch minds ; that there is no difference in their habit of thought, or rather in their mode of expressing thought — for it amounts to no more — that is not explicable from quite minor peculiarities in the social conditions of the two countries ; that in the objects of their intellectual interest and the fundamental lines of their method there is a marked agreement ; and, therefore, that the present inquiry must extend to both. No proof of these positions can be offered now, though a single point may be noted in passing. The modern Scotch thinkers, with rare exceptions, have been, like the German, professors, enjoying, in their own measure, the stimulus of a free university system. The repre- sentative philosophers of England, on the other hand, have been, with hardly an exception, non-academic in position, or even, many of them, anti-academic in feeling. It is a fact of no small significance, though it would be misunder- stood if taken to mean that English thinking is by nature a mere reflexion of practical life. There was a time, long past indeed, when in England also the highest thought of the country found its utterance in the teaching of the universities, and such a time may come again. Nay, are there not signs that the day of professors is once more at hand, if not already upon us ? In gauging, historically, the philosophical performance of the English mind, those who rate it low and those who rate it high err alike, as it seems to me, in contracting the vision too much. Always it is presumed that the first note was struck by the famous Chancellor less than three centuries ago — the note that has been taken up and with mere variations repeated in the generations since ; that, while the fundamental character of English thinking was once for all determined then, it was not at all determined till then ; that before Bacon there was no philosophical thought in England, 32 THE ENGLISH MIND. or none at least that could be called English. And doubtless no injustice is thereby intended to our country in particular, since no claim to a longer intellectual history is put in for any of the other great philosophic countries of modern Europe, unless, perhaps, for Italy ; what thinking there was before the seventeenth century being, in the main, held the property of the one universal Western Church, in whose service all feeling of nationality was overborne by a master sentiment of devotion to the ecclesiastical system. But however plausible this view of pre-modern thought, it is decidedly superficial, no very profound inquiry being needed to discover national character, already in the dim light of that middle age and despite the crushing influence of the Church, asserting itself under the monk's cowl not otherwise, save more feebly, than in the later time, when the nations were free to go each their own way. Or, if there were a, doubt on this point in the case of other nations, at all events, so far as England is concerned, there should be none. I proceed first of all to show, as briefly as may be, how actively the English or British intellect was at work in an age long before Bacon and towards a result which he and his followers are commonly thought to have been the first to conceive. Should it appear that men from these islands were the most forward spirits in that early time and led the van of European thought, the fact is one not to be forgotten in an attempt to take the intellectual measure of our country. If, further, it appear that the British thinkers were the first to break down a system of thought which British thinkers had been among the first to build up, and in so preparing the way of modern thought took ground in the manner of their better-known compatriots of a later day, the fact is one to be carefully impressed. I find the most distinct evidence that our people was from the first to be seen pressing forward in the intellectual race with a clear notion of what it would be at. No nation has kept more steadily to its line of thought, and that is not denied ; but, also, none perhaps has thought so persistently. We seem to have had a line before any other modern people. The scholastic philosophy, so greatly derided in the eighteenth century by those whom it no longer affected, THE ENGLISH MIND. 33 and who for the most part knew nothing of the object of their scorn ; so fiercely opposed in the sixteenth and seventeenth centuries by those whose whole mental action was an open revolt against its authority ; but in still earlier centuries not less passionately espoused and extravagantly esteemed than it has ever been resisted or scorned — is the name for a body of thought worked out and a method of thinking pursued in more or less irregular fashion by ecclesiastics in the West of Europe during some six centuries until the fifteenth. The work of clerics for an avowed theological purpose, it yet covers all the philosophic activity of Christendom in those ages, because the Church — I mean the Western Church, for the Eastern was idle — drew to her- self, trained and used all the thinking power of the countries under her sway. We are now perhaps in a position to judge of this philosophy, or at least can do so with better knowledge than was had in the eighteenth century and with more impartiality than could be felt in the seventeenth. That it was one of the highest achievements of the human mind, cannot be said. Though it took as much time in the working out as Greek philosophy and modern philosophy put together, it must count in the whole history of mental endeavour for greatly less than either. Wanting the reality and exactness of modern positive science and the depth of modern philosophic insight, it was not less devoid of the genial freshness and originality of Hellenic thought. What principle of growth it ever exhibited it was largely beholden for to the influence of Greek ideas, while itself had to be thrust aside to make way for modern knowledge. Neverthe- less there is another side to scholasticism, — one that has been far too little regarded by its detractors, and has moreover escaped the notice of most philosophical historians, while for obvious reasons it is not brought into relief by Catholic teachers who still in these days think with the schoolmen and accept their philosophy as valid and unsurpassed. Sad as it is to think of the huge break in the path of advance of the human intellect — of some ten or more centuries, each a hundred years long, though in stalking over them we forget it, lying all so barren of intellectual fruit between the few bright centuries far off in which the tiny race of Greeks at 3 34 THE ENGLISH MIND. a corner of Europe raised so many deepest questions and went far to settling some, and the two or three busy centuries close at hand in which the leading European nations side by side, first having come back to the old Hellenic point of view, have so widely extended the bounds of knowledge in the way of positive science and so profoundly scanned its bases in the way of philosophy — yet can we not blame schoolmen for being born into that middle age. But, rather, because we know in what a night the light of Greek thought after flickering more and more feebly in the first centuries of our era was finally quenched, while the nations were locked in death-wrestle and the great world-empire, falling into pieces or rent asunder, was being hewn into the first rough shapes of modern nationalities, should we deem it something that thinking began again at all, and more that, in thinking as they could not but think from the ground of blind faith where they stood, priests and monks should have been found not loath but eager to turn full upon their faith the light of old reason as it again broke slowly in from outer parts. All the world has heard of scholasticism as an oppressive system of pedantic belief : it has still to be known as a system of rationalism struggling to be. Few have any notion of the seething mental activity, fatally narrowed, no doubt, in its objects, of the eager questioning and even the muttered scepticism, buried away in the depths of that credulous age. Let us take scholasticism for what it was — the best that the European mind in a hard time was able intellectually to effect, and see, then, what was the part played in its de- velopment first and last by countrymen of ours. When about the year 800, Charlemagne, having brought some- thing like order out of confusion in the West, made his grandiose attempt to organise European society upon the basis of a double-headed supremacy of Emperor and Pope, and bethought him of setting up monastic schools to soften his rude people, it was in the old-established seminary of York that he sought for a director of public in- struction and found his man in Alcuin ; never at the worst had there been a time when at scattered points over these islands a feeble flame of learning had not been kept THE ENGLISH MIND. 35 burning. When two generations later a thinker ot real eminence appeared, the first in four centuries since the time of St. Augustin, and after all that interval began a second era of Christian thought as St. Augustin had closed the first, starting the problem of a rational interpretation of the faith which the school-philosophy was a long and weary series of efforts to resolve, the thinker was John Scotus Erigena sprung from the north country or from Ireland. When two centuries more had passed of blank confusion in Church and State, in the midst of which Christendom well-nigh went down, and again a beginning was made of intellectual progress, with better chance of continuance, the centre this time being Paris and the leading spirits French- men, on no field whether of wordy dialectic or mystic con- templation did our countrymen hang back ; and when in the twelfth century the first race of scholastic wranglers, subtle as they were, had by reason of their failure to con- firm the faith won hardly more credit with the Church than they can gain respect from us, with their clearly manifested impotence to break open new paths of knowledge or even to reconquer of themselves the domain held by the Greeks, an Englishman, as was fitting, John of Salisbury, stood for- ward to speak of leaving verbal quibbles for practice, at the same time that he pointed to Aristotle as the effective guide to larger fields of knowledge. So, again, when with the thirteenth century the Church after its long struggle with the civil power from the time of Hildebrand to the time of Innocent III. had corne forth supreme, had arrayed its standing armies of mendicant friars, and founding regular universities was prepared to uphold and spread its power by dominating education and turning to its own uses the weapons of worldly wisdom, specially that philosophy of Aristotle which as it gradually became known from infidel Arab sources was wrested by some to infidel purposes — another Englishman it was, Alexander of Hales, who first struck into that path of systematic reconciliation of faith and reason — of Church-dogma in its most particular form as elaborated in twelve centuries of Christian effort, and secular knowledge in its widest extent as compassed by the encyclo- paedic labours of the great heathen sage, which was con- 36 THE ENGLISH MIND. summated after the middle of the century by Thomas Aquinas. And once more, when in the Angelic Doctor's rational expression of the Church's faith the work of Scho- lasticism seemed to be accomplished, as, accordingly, that expression has ever since then preserved an authoritative character in the Romish Communion, by whom should the concordat be marred almost as soon as framed but by John Duns Scotus, and in a few years more be quite torn up but by William of Ockham, both Franciscan monks from this country ? Nor, though he stands aloof from the main current of scholastic thought which here has been traced, is the name of another Franciscan, from the thirteenth century, to be passed over : Roger Bacon, almost the only man of his age, to whom the world of nature seemed, as it seems to us, the great quarry of human intellect, rather than a realm of evil from which the faithful, banned into it for a while, cannot too much turn away their eyes, may fitly close our roll of English thinkers in the middle age. It should now be clear, even in such a rough tracing, that from the earliest appearance of modern national divisions and during a full half of their history, men of our race played a part of quite singular prominence in the general intellectual move- ment of Europe. Almost might one say that as long as the movement, from taking place within the fold of the univer- sal Church, was in the strict sense a collectively European one, the start at every new stage of the course was due to the initiative of a British schoolman. And there is more to be said. As scholasticism is now of most interest as itself but a stage — not a bright one — in the whole intellectual course of humanity, what is of prime concern is how the passage out of it into the next was made ; and at this crisis, while men of English name become more prominent than ever, a certain distinctive character begins to be apparent in their philosophic action. The prominence before, when mediaeval thought was beginning from nothing, might be accidental ; the English were a little better schooled, per- chance because they lay out at sea, and then, as often later, had comparative peace, while the continent was in trouble. But long after, when an elaborate system of thought had been worked out. which, though it realised an ideal strained after THE ENGLISH MIND. 87 through many generations, was no sooner an accomplished fact, than it must have seemed as a ponderous net thrown over free intellectual effort — that then the men who sought to cast it off, should all have sprung from the same soil, looks to be other than accident. Such action must have been natural to thinkers of that origin. Now, besides Koger Bacon, who for his interest in external nature is at once recognised as of English breed, and is readily supposed as in conflict with the spirit of his age, the schoolmen that broke away from the system that satisfied the highest aspirations of Churchmen in the thirteenth century are the two, John Duns Scotus and William of Ockham. It is worth while to look a little more closely into their mutiny. The younger, William of Ockham, is the more impor- tant figure. Scotus, indeed, the terrible dialectician who refined and distinguished beyond all human belief to the ex- tent of some twelve folio volumes before he was laid in his early grave at the age of thirty-four, was a most devoted son of the Church ; and when he disturbed the settlement of Aquinas by denying that there could be a rational insight into the mysteries of the faith, did it expressly with the view of aggrandising the authority of the Church in the person of the Pope. With William of Ockham it was otherwise. Monk as he was, that rebellious spirit was the sworn enemy of papal pretensions, and though he also professed to bow in matters of faith to a Church whose creed he pronounced incapable of rational proof, in him, it hardly can be doubted, we come upon one, perhaps the first within the Church, more concerned, like a mere philosopher, to draw the line between science and ignorance, than as a theologian solicit- ous about establishing the faith. And for certain, in this English Franciscan, still deep in the middle age, three long centuries before the day of Bacon and Hobbes, we can des- cry, through the veil of his scholastic jargon, a thinker mentally akin to these — to Hobbes especially — in a fashion of which they in the indiscriminating impatience of their opposition to the scholastic system little dreamt. One might even marvel that 300 years should have had to drag out their slow length before the advent of modern thought in the seventeenth century, when this English schoolman in the 38 THE ENGLISH MIND. fourteenth had so signally cleared the way for it, did not one gather but too unmistakably from the history of effective human thought, broken from the ancient to the modern time for 1300 instead of 300 years, that among the forces which in their shock make general human history the force of mere intelligence is far from being the most powerful. Much had to happen in the great world before philosophical ideas from which Ockham's were not far removed in sub- stance, however much in form, could be enunciated so as to pass into the train of modern intellectual life ; or before Lord Bacon could amid the applause of men preach that experimental investigation of nature for trying to practise which Friar Bacon in the thirteenth century had to sit long years in a dungeon and endure the bitterness of neglect. The fact notwithstanding remains memorable to us, that in the earlier time English minds were impelled as by some strong national instinct to work towards the far distant future ; for it was not less the same instinct, because in Roger Bacon it assumed the guise of a craving after free search into nature, while in Duns Scotus it betrayed itself as an extra- vagant supernaturalism overshadowing science, and in William of Ockham it took the form of a critical scepticism looking askance upon theology. In all three it was a prin- ciple of opposition to the attempt to determine dogmatically how things must be, to measure the universe by a crude rational system. It was as if Roger Bacon said : Let not man by mere thinking or superficial deduction dream of penetrating to the inmost recesses of nature ; as if Scotus said : Let not man dream of thinking out a highest rea- son of things — such he must take on faith ; finally, as if William of Ockham said : Let man be content to inquire within the limit of his powers, and let him mind his steps even there. But to English ears that is a familiar strain ; for it is the strain in which the leaders of English modern thought have spoken. Bacon, Hobbes, Locke, Berkeley, Hume — such in the modern period is the succession of great names unbroken for 150 years, which represents the eagerness and persistence of philosophical effort in England ; which represents also, as I think, with a singular completeness and consistency, the THE ENGLISH MIND. 39 various possibilities of English thinking-power. Is it meant, that there are none, — that there never have been any, — among us, who renounce all such intellectual leadership ? Is it meant that contemporary with these there were no other, — there were not many other, — names worthy to take rank by the side of them ? Or, once more, is it meant that in the hundred years since Hume, we have been content to let him and these his predecessors think for us, and have not gone beyond them in logical method, in psychological analysis, in moral prescription, or in grasp of philosophical principles? Nothing of all that is meant. But it is meant that in every generation the thinkers or the philosophic writers amongst us who stand up for other principles than these in the main agree in representing or who acknowledge other masters, seem to rise and pass, leaving few traces of their work behind ; that in the time of these, other names of repute are cast into the shade by them ; and that in the later time the great advances that have been made in every field of philosophic thought, have been made so much upon the line and in the spirit of their inquiries — even the thinkers of the Scottish school having loudly vowed allegiance to Bacon — that it is needless, for estimating the scope and character of English thinking, to come down farther than to Hume. Hume's importance, in closing the series, lies in the fact that, till he appeared, the ques- tioning faculty of the English mind, in its full subtlety and daring, stood unrevealed. William of Ockham had questioned boldly, but the memory of him perished amid the ruin that he wrought, and modern thought proceeded with- out the least regard to his foregone and forgotten scepticism. In Hume the revelation was such that no philosophical construction, since his time, in England can pretend to stability, if made without heed to his critical scrutiny of the grounds of human knowledge, while, on the other hand, any construction that has been raised beyond his power to over- throw cannot be very unstable. This is but another way of saying over again that later English work in philosophy —superior though it perhaps is to the work of those earlier thinkers — may for our present purpose be discounted. Now the five thinkers named from Bacon to Hume, whatever 40 THE ENGLISH MIND. their difference of individual character and aims, display a greater general similarity of intellectual vision than can be matched, for such a succession of first-rate minds, from the history of any other modern people. The contrast presented by the course of thought in other countries is indeed quite remarkable. Thus in France the high speculation of the seventeenth century gave place in the eighteenth to obser- vation of the soberest cast, this in turn yielding to higher speculation than ever in the nineteenth, till in those latest years inquiry of a positive sort has again begun to prevail. In Germany though there have been no such Gallic revolu- tions in the philosophic any more than in the political sphere, but rather the great systems of thought, as they have succeeded each other, appear singularly uniform in character, yet upon a closer view the distance is seen to be enormous from the dogmatism of Leibniz to the critical spirit of Kant, or again from Kant's sober reserve to the stupendous confidence of Hegel ; while after the lapse of 150 years from the time of Leibniz, a general change of face may be said to have been made at last. No change of face is visible throughout the course of English philosophy, and we may truly express its general character in trying to express the common thought of our 6ve representative thinkers. That human knowledge is a deposit from particular experiences ; that it is strictly limited by the narrowness of human intelligence, which means that the sources of ex- perience are in number fixed and that not great ; that it is not more sharply defined outwards than it needs to be carefully elaborated within ; that any attempt at extension of it, which is theorising, must never be more than a temporary anticipation of experience, to stand or fall as verification can or cannot be found ; that it is to be sought after chiefly for the power it gives of bending the nature of things to human ends, as these can be best conceived ; that where attainable it is to be sought absolutely without heed of human prejudice or authority ; but that beyond nature which is thus and not otherwise to be known there is a region of the supernatural the relation of which to nature is not apprehensible by human reason and which -altogether is to be accepted on faith. Such seem to be the main ideas THE ENGLISH MIND. 41 of these English philosophers. It is not that all were put forward into equal prominence by each thinker, for the different aims of each could not in the same way be furthered, and the conception of some of the five was more profound than of the others ; but this may be said, that the most coldly secular, the most sceptical, minds among them re- cognised, or made as if they recognised, beyond the sphere of natural experience and knowledge a sphere of super- natural interest, while the least worldly-minded of them — a,nd one there was of almost faultless sanctity of soul — had for science an eye as sharply critical and a view as practical as any of their fellows. Of that mystic enthusiasm which when it is not impatient of all special knowledge substitutes a vain imagining for the laborious work of observation and reasoning, less is to be found in Berkeley than in any other saint. Of that mere worldly concern which is begotten of an interest in massing the facts and searching out the laws of external nature, or in tracing the growth of mind in its dependence upon external conditions, as little is to be found in Bacon or in Locke as in any other empirical thinkers. Or of professed, and perhaps real, regard for a sphere of interest surmised beyond the mundane region, especially when it is considered how inexorably they confine -the mind to the knowledge of mere phenomena, there is not more to be seen in any minds of secular cast than in Hobbes and Hume. In all five the likeness of common feature to later English thinkers as well as to those early schoolmen, called up to- night from their sleep of centuries, is beyond dispute ; and with their philosophic work in view we may now proceed, in •conclusion, to draw out one or two of the more -predominant aspects of English thought. In the first place, then, no philosophy has come to terms, like the English, with the positive sciences ; and that should be held a note of honour, if philosophy, as opposed to special science, claims to direct all human energies because it con- sciously comprehends them ; for what cannot be doubted is, that the positive investigation of nature is the special work of modern times — the task to which we are irrevocably •committed now, .as to it we were -irresistibly driven from the first. As little can it be doubted that English philo- 42 THE ENGLISH MIND. sophic thinking is of the cast here indicated. Bacon's philosophy remains the stirring trumpet-call to modern scientific action, even when we hold it, as we must, by no means the true plan of campaign. Hobbes's philosophy is a premature attempt to be itself a body of the special sciences, ordered upon a principle and directed towards a practical end. Locke, with his perfect modesty, holds it for himself ' ambition enough to be employed as an under- labourer clearing the ground a little ' for ' master-builders,' as he calls them, of the strain of Boyle and Newton. So Hume, when in lofty phrase he aspires to 'march up directly to the capital or centre of the sciences, to human nature itself,' and master that in his philosophy, has but this in view, that men may thence sally forth to make wiser and surer con- quests in those fields of special science lying all about. And Berkeley, the pure spirit, breathing the air of mountain-tops, after the fancy of some ; the moon-struck destroyer of the solid frame of earth according to the indignant or con- temptuous common-sense of others — why, he, indeed, is at war with the men of science — Newton and hia following — but only because of the rash liberties which, as it seems to him, they presume to take with the natural world of fact, and their precipitate theorising when ex- perience should be taken as all in all. Now, with this attitude of English philosophers towards the laborious work on the fields of natural science, contrast for one moment the impatience of Leibniz, and Hegel's haughty disdain of the ' barbarian ' Newton and his ' pitiful ' ex- perimenting. Whether the famous German judged rightly,, as he certainly judged from a height than which no man has ever mounted higher, this is not the place to consider : he would be a bold man who should rashly say that he judged wrongly. But it may not be amiss to mention that in Hegel's own university of Berlin, within ear-shot of the academic chair whence his contempt of all English think- ing and science for long years was wont to be poured forth,. I have heard Newton spoken of as the greatest head the world has ever seen. Whether, again, this was the right judg- ment I can as little here venture to decide. Yet that it should have been pronounced in the very citadel of German specu- THE ENGLISH MIND. 43 lation by a man of the first scientific mark does seem a rather striking tribute to the English habit of philosophic thought with which science of the Newtonian stamp so freely passes current. But again this English philosophic interest in the positive sciences has had one striking effect — it has reacted upon the method of philosophic inquiry itself and tended to make this scientific : unless it be that we rather have here two collateral results of one natural disposition in the English mind. By scientific method in philosophy, I mean that in our highest efforts to comprehend in unity of thought the vast universe of being and to divine the origin and destiny of humanity — which is philosophy — we seek to proceed not by way of arbitrary speculation but from a basis of evident fact, we seek even more to bring all our reasonings face to face with fact as their final test, and always act as if we believed that to no one man can it happen that he should tear aside the veil and once for all lay bare the hidden mystery of existence, but that only by the united labour of many men and the continuous labour of many generations of men, as in the modern science of external nature, may the corner of the veil perchance be lifted higher and higher up. Now the philosopher's facts are facts of mind, or all possible facts taken, as all ultimately can and must be, as they are mentally experienced : and when such are scienti- fically investigated, there is psychology. This then is a second point : English philosophy is psychological. How true this is, and also how distinctive the description is, nothing could be easier than to show. From the time of Locke at least, if not of Hobbes, English thinking has been nothing if not psychological. And so, when other countries — France in the last century notably, and more than once in this, Germany in the last century also, though not in its foremost thinkers and therefore obscurely, but in the present century more and more signally within the last generation — have turned into the psychological path, English influence, not hard to trace, may always be seen at work. They have often laughed, Germans especially, from the height where they were labouring to fly, at our sober march below — as if much groping along nether ways 44 THE ENGLISH MIND. could call itself philosophy ! they have sometimes (it is worth our looking to see whether not now), getting upon the path by our side, truly strode forward while we were creep- ing. But at all events our march has not been broken ; and the path we may call ours. Once more, ours is a moralising philosophy. Not that the representative thinkers are moralisers by profession — for that is the business of weaker philosophers or other men ; they are not even all moralists, which is something very different : and yet the phrase is fitly applied, if by moralising is meant the habit of turning all things to the account of human conduct. The charge has been laid against our whole literature that a vein of sermonising runs every- where through it, the highest artistic effect being constantly missed that some practical lesson or other may be enforced. And certainly our philosophy or truth-seeking, while it has recommended and fostered the science which makes man master of the powers of nature to wield them for his ends, has also in its more immediate sphere been for- ward to draw from the limits of human knowledge the lesson that in good practice, far more than in vain search after the inconceivable, man best works out the possibilities of his being. And now, in a word, to end as we began with our pungent but not unfriendly critic — a man whom the sombre vision that he conjures up has not deterred from working quite lately, with a genial power of his own, in the very track of English psychologists, and who more than any other is helping to restore the influence of English philosophical thought in France. Shall we accept his view of our position — that picture of the yawning abysses with tremulous mortals peering over the verge into darkness, and for want of sight, putting wild or gloomy fancies there as they draw back to sate eye and heart with the things of sense ? We need not accept the picture, though we may have come to be able to conceive how it should have been painted. Its main lines are an attempt to portray a mental attitude which we have found some historical reasons for ascribing to the thinkers of our name. But the action gives a suggestion of helpless despair, and the colouring has a tone of gloom, THE ENGLISH MIND. 45 that are imagined. Men of another name, it is adroitly hinted, are in a brighter case, have far glances into a region of light and see the things that are near with other eyes. It is hinted, but it is far from being made out. And if that is not made out, still less is justice done to the per- tinacious ardour with which, as we have now seen, English thinkers have through ten centuries again and again essayed to face the mystery of the universe, or to the true philosophic wisdom with which, bowing the head at every repulse before the impregnable, they have turned to search out with a sterner determination the untold secrets of nature to which they held the key, and to do better what their right hand found to do. That, as it seems to me, is the characteristic note of English philosophy. THE SENSES.1 SUPPOSE, by a wild stretch of imagination, some mechanism that will make a rod turn round one of its ends, quite slowly at first, but then faster and faster, till it will revolve any number of times in a second ; which is, of course, perfectly imaginable, though you could not find such a rod or put together such a mechanism. Let the whirling go on in a dark room, and suppose a man there knowing nothing of the rod : how will he be affected by it ? So long as it turns but a few times in the second, he will not be affected at all unless he is near enough to receive a blow on the skin. But as soon as it begins to spin from sixteen to twenty times a second, a deep growling note will break in upon him through his ear ; and as the rate then grows swifter, the tone will go on becoming less and less grave, and soon more and more acute, till it will reach a pitch of shrillness hardly to be borne when the speed has to be counted by tens of thou- sands. At length, about the stage of forty thousand revolu- tions a second, more or less, the shrillness will pass into stillness ; silence will again reign as at the first, nor any more be broken. The rod might now plunge on in mad fury for a very long time without making any difference to the man ; but let it suddenly come to whirl some million times a second, and then through intervening space faint rays of heat will begin to steal towards him, setting up a feeling of warmth in his skin ; which again will grow more and more intense, as now through tens and hundreds and thousands of millions the rate of revolution is supposed to rise. Why not billions ? The heat at first will be only so much the greater. But, lo ! about the stage of four hundred billions there is more — a dim red light becomes visible in 1 A Lecture delivered in the Hulme Town Hall, Manchester, on Wednesday, 3rd December, 1873. THE SENSES. 47 the gloom; and now, while the rate still mounts up, the heat in its turn dies away, till it vanishes as the sound vanished; but the red light will have passed for the eye into a yellow, a green, a blue, and, last of all, a violet. And to the violet, the revolutions being now about eight hundred billions a second, there will succeed darkness — night, as in the beginning. This darkness too, like the stillness, will never more be broken. Let the rod whirl on as it may, its doings cannot come within the ken of that man's senses. This experimental fancy — rather apt to take the breath away — I quote from the German books where it is to be found, because it brings into line, in a striking way, the most of what physical science can tell us about the senses, and at the same time suggests a number of questions, which, though they go beyond physics to answer, are among those that we must try to deal with this evening. Physics, as you know, is the science treating of nature, or the world of matter ; and it explains what it can of the changes or pro- cesses going on there by resolving them into motions, under some general laws that have been very certainly determined. Now a great part of all the changes in nature are in the sensible qualities of things, such as their colour, temperature, and the like ; and for all the variety of these the physical inquirer seeks out an expression in terms of motion. That in the objects sound, colour, &c., are motions, however they may appear to particular senses, was long ago surmised ; as, indeed, in the case of sound, which first began to be under- stood, the fact is often quite evident. Sonorous bodies like a bell or a drum or a musical string are plainly in motion, which may pass to other bodies, and in particular by one great body, the air, can be carried a long way. The motion in bodies when giving forth light or heat, and the medium — not air — which is the general bearer of that motion, have been much less easy to determine ; but modern inquiry has practically mastered the difficulty, and the tremendous figures given in our fancied experiment are some of those assigned in all soberness for the number of vibrations per second in the all-pervading ether that go with simple sensa- tions of heat and colour in us. There is no expression of 48 THE SENSES. the same definite kind for tastes and smells ; the process- there being of the chemical rather than of the mechanical sort. But a chemical action also is, in the last resort,, intelligible to us only as a mode of motion ; and thus we may say that all sensible qualities are resolved by physical science into motions in the objects. In touch, which has- not been mentioned, the action is mechanical of the most apparent kind. Now, coming back to our rod, whose whirling is supposed to communicate to the air and ether in the room motions, of like rate to those caused in fact by sounding, hot and shining bodies, we may remark two things strange. The first is that its motion had no effect on the man except at particular stages, and within a definite range at each. Putting always aside the case of actual contact as practically out of the question, we note the blank before the first deep groan burst forth, the tremendous blank when the last, screech had gone out until heat began to steal in, and again the immeasurable tract lying beyond the limit where light passed into darkness. The second fact is, that within a certain range the motion appeared differently as both heat and light. Why should one rate of the motion appear only as sound, another only as heat, and another only as light ? Why should other rates among or outside of these not appear as anything at all? And why should one rate appear doubly as both heat and light ? These are questions that do not concern the physical inquirer, whose work is done when he has got the sensible qualities into expressions admitting of definite measurement. But we must try to find an answer for them. There can be no doubt in what direction we have first to look. The question is why bodies outside of us affect us in certain ways and not in others. Well, of course, that depends on our capacity of being affected. Our physical frame or body offers itself to be acted on by other bodies in motion, and the result in the first instance must depend upon what organs and what kind of organs it has for receiv- ing the motion or stimulus. This it is the business of a different man of science, the physiologist, to determine ; and within the last generation or two — not earlier — a great THE SENSES. 49 deal has been done for the physiology of sensation, however much remains to be learned. In regular sensation, as of a colour or sound, there is an invisible disturbance in some part or parts of the mass of the brain within the skull. This disturbance results from an ingoing wave or current of invisible motion along the white fibrous lines called nerves. This wave or current begins at the outer ends of the nerve-fibres, where they are in conjunction with various microscopic structures, partly nervous, partly other than nervous ; and these structures are reached by the exciting stimulus (which we have seen to be some motion, visible or invisible, in external bodies), through the parts or openings on the surface of the human body — eyes, ears, and the like — which are commonly called the organs of the senses. It is a very complex process alto- gether, and for true sensation all the stages are of account ; yet some are easily seen to be of greater importance than others. Least important is the part played by the external organs, for these are often injured without sensation being stopped. Most important is the action of the brain, without which there can be no conscious state at all. For the rest, let us carefully distinguish between the nerve-fibres going to the brain and their endings in the minute structures. Nerve-fibres, by themselves, are mere conductors which, like telegraph-wires, may carry indifferently in either direc- tion, and, though in the actual nerves, which are compound bundles of fibres, they carry only one way, they will carry any sort of disturbance, whatever it be, that is strong enough to rouse them at all. Thus the optic nerve may be excited by any strong pressure, and is not excited when acted on directly by the proper stimulus of light, which happens to be a very weak one. In short, the fibrous lines of nerve seem not to determine the character of the sensations had through them, any more than a telegraph-wire determines the import of the message sent along it. But, if the mere nerves are practically alike in structure and function, most varied is the structure of their endings at the outer organs. The endings in ear, and eye, and skin are quite different ; and, again, at different parts of the same organ — as between the middle and sides of the back of the eye, or between the 4 50 THE SENSES. finger-tips and skin of the shoulders in the organ of touch — the variety of structure is very great. Note this second point, because we shall come back upon it later. It is the first point that concerns us now. Besides the fibres, it should be observed that the nervous system includes another sort of matter, consisting of darker- coloured cells, extremely minute in size. These cells, wherever found — in little gatherings here and there, or compacted into a column at the heart of the spinal cord, or massed variously at the base of the brain, or packed away in the winding folds next to the skull-cap — are storehouses of pent-up energy, ready, upon the least excitement, to burst forth as invisible motion along fibrous lines laid from them. The fibres are in substance much less unstable, and besides, both singly and as done up in bundles, or again in the sets of bundles which are called nerves, are protected by sheaths along their whole length, the ends only being left exposed. Now, as the brain buried away in the skull is, in the regular process of sensation, thrown into action only by the disturbance sent up along the nerve-fibres from their tiny ends thus unprotected, the stimulus applied here must either be very strong in itself, or, if weak, must some- how be strengthened to produce an effect. And strong enough it sometimes is, as from a violent blow or burn on the skin, destroying the very tissue of the nerves where they end, and thence, by way of the spinal cord and brain, throwing the whole frame into convulsive spasms. More commonly however the natural stimulus, as we had already occasion to remark of light, is very weak. What strength, do you suppose, is there in those inconceivably minute ether-waves that reach us after travelling years and years through space from a glimmering star of the sixth magni- tude ? Or what violence is there in the air-waves bringing tidings that a pin has fallen on the floor ? Unless there is some means of intensifying or multiplying the stimulus, it will tap in vain even where the sluggish fibres present open ends to it. Now, practically, there are such means. Specks of the grey unstable matter are found at many places joined with the fibre-ends, able to catch a stimulus too faint to be of any avail against the lazy indifference of these. It is as if THE SENSES. 51 an anxious inmate of a house, eager to learn news of some event, but unable to stir abroad, and distrustful of the porter at the door, should keep on the watch outside a small boy of his own flesh and blood, eager like himself, who should arouse the sleepy doorkeeper on every the least occasion. Other structures also are found in the eye, that seem to make the signal more marked by first changing its character. In the ear there are various devices increasing the effect on the nerve-filaments. Under the skin, wherever touch is delicate, hard little bodies are disposed, doing regularly for the fibre-ends what happens when a thorn finds its way there. To give you any idea of the delicacy and variety of the arrangements is here impossible, not to say that much still remains to be learnt ; but there is this broad fact to be taken along with us — that the regular stimu- lation from natural agents, often a most gentle motion, is taken up at all by our nerves only when it has first been variously modified at the points where these stand exposed. Let us now recall the questions forced upon us by the rod-experiment. First, there was that strange fact of breaks or blanks in sensation, with perfect continuity of physical stimulation. May we not say now that a great deal of stimulation can easily be lost upon us for want of proper means to take it up by the nerves? It is a question, at least at the first stage, of mere physical correspondence. You strike a string in one piano, and a string in another close by begins also to vibrate, while other strings remain quite still. So the nervous system, through the nerve- endings, responds with action of its own to some rates or kinds of physical motion, and does not respond to ether- vibrations above those of violet and below those of heat, or air- vibrations outside a certain range ; because the eye, and the skin, and the ear, in those essential parts of them through which the nerve-fibres are affected, are constituted not otherwise than they are. Thus also may we account for the different sensibility of different people. Some hear sounds at both ends of the scale that average ears never take in ; and others, with ears of less than ordinary compass, never hear a bat squeak or a cricket chirp. The like is true 52 THE SENSES. of vision, and the common fact of colour-blindness, blotting out for so many people some colours entirely, is now as- cribed to tbe absence of certain of the minute elements in the retina or sensitive curtain at the back of the eye. And what is total deafness or blindness? This may be due to defect in the central organ of the brain, but also, though centres are intact and the nervous communication is perfect, let the truly sensitive parts in ear or eye be only a little changed, and then, while air or ether may surge and eddy as before, the clefts that were in consciousness will have become chasms, engulfing the sensible glory of the world. The other question was how the same physical stimulus could at the same time be the occasion of sensations so differ- ent as heat and light. Well, but what a difference of organ there is at the skin and in the eye ! If there is any meaning at all in speaking of bodily conditions for mental states, it is impossible not to connect with the difference of the minute structures under the skin and at the back of the eye both the fact that at the extremes of the whole sensible range ether- waves are caught up by one line which are not caught up by the other, and also the fact that within a certain mean range the same waves are caught up differently towards a different conscious result. See what takes place in another organ — the tongue. Through the tongue, at its tip, we not only taste, but also have a finer sense of touch than even in the fingers, and the curious thing is that the double duty is there done by a single nerve — not different nerves, as for heat and light. How can the same nerve, say from the same lump of sugar, take on impressions so different as sweetness and roughness ? Perhaps the micro- scope tells when it tracks part of the fine nerve-filaments to little structures known from the analogy of the tactile organs elsewhere to be serviceable for touch, and part into little cup-shaped openings, which are most probably the nerve-endings for taste, since we know that in order to be tasted substances must first be brought to the state of liquid solution. After that the case of heat and light, where the organs are so very unlike, cannot at least be thought strange. The skin within itself presents still another in- THE SENSES. 53 stance of double sensibility, contact and temperature, which some would make treble by adding (in my opinion errone- ously) a sense of pain. Whether it is here enough to suppose the nerve-endings the same and only the mode of stimulation, as it in fact is, different ; or whether there must be supposed peculiar nerve-endings for each sensi- bility, are questions to be decided by positive evidence when it can be got. It may now occur to some of you as not so difficult, from this point of view, to conceive of a great increase in our sensible experience, by merely supposing us to have other organs, or the present organs slightly varied, for catching up the stimulation that plainly is lost upon us. Why should our senses be limited to five, or some such number? Voltaire, in one of his tales, has a humorous fancy of people in Saturn with seventy-two senses, visited by a wanderer from the region of the Dog-star with the decent outfit of a thousand. Why not ? Under our own eyes do we not see the lower animals often acting in a way that means, if not quite other senses than ours, at least senses of quite another range? But we must not stray into ques- tions of that sort, when there are others pressing more to be answered. For, now that we have taken from physiology a rough notion of what happens in the human body, as before we took from physics a rough notion of what happens in external bodies, when there is sensation, we are still rather at the beginning than the end of our inquiry. Colour, for instance, which appears to be in bodies but is not there except as a dance of particles, which is had only through the eye and brain but is not there except as a current and explosion — is what in itself? And if not in the thing called coloured except in appearance, why does it so appear? Neither physics nor physiology can tell, but only, if at all, the science of mind, which is called psychology. I say "if at all,-" because even the psychologist will tell us what sensation is not, rather than what it is. This, however, is not surprising, for neither does the science of physics tell what motion is, but only takes it as a fact and discovers its laws. If this is all that can be done for something so evident as motion, much more may we expect it of a mental 54 THE SENSES. process like sensation, that cannot in the same way be made evident. The psychologist can search out and classify the kinds of sensations, can show many of them to be much less simple than they at first appear, and can discover the laws according to which they combine to ever new results. It is before the fact of sensation itself that his science, like all others, breaks down. There is nothing simpler to ex- press it by. It is sometimes said that sensations are signs in consciousness of events that are constantly occurring in the material world ; but though this saying has a good meaning and is true, it makes nothing plainer. The diffi- culty turns up again in the word consciousness. In fact, we are here face to face with the great mystery of our being, and must bow the head. The psychologist tries rather to comprehend how sensations, with other elements of con- scious experience, conspire towards the inexpressibly varied result of our full mental life. Now sensations enter chiefly into our apprehension of the vast material universe stretch- ing away on all sides from us, and the main question as regards them is how that can be. Let us take the question in the simpler form that occurred to us before. Colours and the like, which are not in things nor in the brain, but in the mind or consciousness, appear to us all to be in the things. Why? It is no sufficient answer to say that as there is nothing but sensations in the mind — no direct apprehension of motions in the objects or organs — the mind can put into objects nothing else. Why is any- thing put outside at all ? I cannot hope to give anything like a full answer to the question even in the simplest form; but some things may be said that have an important bearing on it, and that should in any case be stated in giving an account of the senses. First of all observe that by no means all sensations are put outside of us into things. Besides the sensations of the five senses we have a great many other simple feelings, often called bodily feelings, and best spoken of under the general name of Organic Sensations, because they are con- nected with the action, healthy or diseased, of the vital organs. Of these none are referred to external objects in the way that colours or sounds are, and only some of them, THE SENSES. 55 like suffocation and hunger, are referred to particular seats in the body. Even in the five senses many states are hardly referred beyond the organs through which they arise. Tastes seem to us in the tongue ; smells, often in the nostrils ; sounds, not seldom in the ear. So also in touch the pain of a cut from a knife appears to us in the skin, and in sight the sensation of dazzling light is rather within the eye than without. The regular sensations of sight and touch are, however, referred outside. Colours always seem as if spread out in space, and distinct points of light appear to stand apart. The sensations of smoothness and hardness from the same knife that caused the pain in the skin, seem to us no states of ours but qualities of the blade. And less regularly sounds also and odours appear to come as if from things. Observe next this other series of facts. While it is generally true of all these sensations that we are passive under them, meaning that in certain circumstances it does not depend upon our will whether we have them or not, there is yet a great difference among them, when they are present, in respect of our power to control them. We often have sensations which 110 action can modify whatever we do; whether we run, walk, stand, or lie, the discomfort continues, and all we can say is that it is " somewhere inside". Other sensations of the organic sort, less vague, and referred to particular seats, as the lungs, or stomach, or teeth, we do have some control over : by general pressure on the parts, or other local applications, we may often alter their degree. Greater, though still limited, is our control over states referred to the organs of special sense : though we cannot at once get rid of pains like those of a cut, or a burn, or a bitter taste in the mouth, we can act very directly to modify them. We can altogether get rid of the smells and sounds that are referred to external things — if not by merely turning the head, closing the passages with the fingers or otherwise, then, at the worst, by getting up and moving bodily away. Most perfect by far, however, is the control over touches and sights. Here there is an action or motion of the organs themselves. What so easily moved as the eye and hand ? We can vary or discard touches and sights at will by simply moving the organs. 56 THE SENSES. What may we make out from the two sets of facts thus running by the side of each other? In proportion as sensations are beyond the control of our active move- ments, they appear or remain with us as mere sensations. In proportion as they appear to be qualities of things, and cease to appear as sensations, they are subject to such control. Till some other element of difference be assigned, it is open to say that the absence or presence of active movement with them makes all the difference. That is not, however, the proper way to put it. It is a difference in our consciousness or mental experience that has to be accounted for, and the fact of active movement is nothing to the purpose if we are not conscious of it. But this is just what we are. Though I have before expressly kept it out of view, there is, by the side of all these sensations, another kind of simple conscious experience — the sense of activity put forth, now commonly called the Muscular Sense. In some respects it is like other sensation, and in some respects very different. It is like in being a simple experience, that is, one that cannot be brought to anything simpler, and also in being connected physically with the action of nerves. It is different in being the consciousness of active exertion, not of any affection passively received, and also on the physical side, because there is reason to believe that it arises in or with the fact of motor impulse being sent out from the brain by the nervous lines going to the muscles, not, like sensation proper, in connexion with nervous disturbance at the surface, which is passed up to the brain. The experience is had in or with all movements that we consciously make through our members, in every case of bodily strain (where our movement is resisted or impeded), in weighing things with our hands, in running over things with the eyes. Bodies as spread out in space and resisting penetration there, also the space we call free between bodies, cannot be apprehended without it. To see this, just watch the movements of a child making the acquaintance of new objects or a new place. I do not say more, because I do not wish to take you beyond the region of facts on to ground that has been disputed among philo- sophers for ages. It is too hard a question to venture on THE SENSES. 57 here, how sensations, when blended with our conscious experience of activity, may come to be transformed into the guise of sensible qualities in things. But we may look a little more closely at the two chief senses — touch and sight — that give us a perception of things as external. We have already seen how touch and sight stand apart from the other senses, and there is still more to say on that head. However we may project outside of us the sensations of sound, or smell, or even taste, it is always into things already supposed tangible or visible, or both tangible and visible. Our world may be called one of sights and touches. An object spoken of comes before the mind first as it would look to the eye, if seen, or to the touch, if felt. This is true even of things that powerfully affect other senses, and have their value accordingly ; for example, a piece of sugar, a rose, a bell. As I uttered those words, did not a repre- sentation of certain visible and tangible forms first rise before you, one bearing sweetness, another fragrance, and the third sound, either in fact or as a possibility? Now, why ? The first remark to make is that, as a fact, all objects perceived by us do, or may, affect sight and touch, while by no means all affect the other senses. Most objects give forth no sound that ever is heard, no odour that ever is smelt, nor ever fall to be tasted. Though it may be, in the first two cases, only because our hearing and smell are not fine enough — though it may be quite different in many of the lower animals — the fact remains true of human beings. Remark next that smells and sounds (we may drop tastes as unimportant) generally, as it were, steal in upon us, without calling for any action on our part to become sensible of them; and, again, that there is a great deal of active movement on our part that brings on no smells or sounds. On the other hand, observe how, in touching and seeing, we are in general actively moving the hands arid eyes ; and, what is still more remarkable, that practically we never move either the body in general, or those most mobile parts of it, the arms and hands and the eyes, as we constantly are doing, without experiencing a variety of sensations of touch and sight. I say in these 58 THE SENSES. circumstances it is impossible, if it be true that bodies in space are apprehended through our muscular activity — it is impossible that their other prominent qualities, besides extension and resistance, should not be supplied by touch and sight. But is it the case that we do not touch or see without moving our hands and eyes ? By touch, with my hand at rest, I perceive this table spread out and hard ; by sight I perceive this hall, and in it people, with eyes kept perfectly still. True, I had to move my hand into contact with the table, and my eyelids to open them ; also, touching this table for the first time in the dark, I certainly should move my hand over it to know what it was, as still I must move my eyes about to take in the hall and people properly. It is the fact, nevertheless, that the mere outspread hand tells of an object spread out in space, and the mere open eye discloses a vast variety of objects. The fact appears quite fatal to our view, and yet I venture to assert that there is no stronger confirmation of it, the organs of touch and vision being what they are. With different parts of the skin we touch quite differently, and see differently with different parts of the retina. Touch is best at the tip of the tongue and tips of the fingers, also in the hand generally. Sight is best within a small area known as the yellow spot, near the middle of the back of the eye. As the retina comes forward round the inside of the eye, it grows less sensitive ; likewise on the skin there is a falling- off away from the hand, greatest perhaps on the back. The differences depend physically on the number of nerve-fila- ments going to the parts, and on the kind of nerve-endings found there, both (as we remarked before of the latter) vary- ing greatly ; but let that pass. In our mental experience the differences appear as some variety of quality or kind in the sensations. Thus an object bright-red, when held straight before the eye fixed, loses in brightness and even in colour as it is moved sideways ; still more an unfamiliar ob- ject, first seen with the side of the eye, has a different look when it comes to be seen through the yellow spot in the middle. So a piece of cloth feels quite differently to the back and to the fingers. There is another and very striking THE SENSES. 59 way of bringing out the difference in touch. Two points of a compass felt as double at some parts seem one at others, and the differences as measured are most surprising. The tip of the tongue feels them double if only they are YV mcn apart, and the tip of the forefinger if only ^ ; but they must be held from two or three inches apart at the back and other places, or they will be felt as one point only. Hence the notion has been started that the skin should be viewed as a sort of mosaic, made up of little areas or plots of varying size — very small and closely packed at the sensitive places, and comparatively large elsewhere — each having its own quality of touch, not the same as at any other. Though the view has never yet been stated in a perfectly unexceptionable way, the idea conveyed as to the varying quality of the sensations is, I consider, substantially correct. Whenever two touches are distinguished, it must be because of some difference between them in consciousness ; and the only difference that can be at bottom is of the kind called quality. We distinguish tastes by their quality, smells by their quality, sounds by their quality ; and the different quality of musical sounds is now believed to depend on the different nerve-fibres affected. Why not also in touch, where there may be a difference, not of nerve-fibres only, but of nerves ? I hold that in many cases we do actually feel the difference of quality, and that where we do not it is because the differ- ence comes, as we shall see, to mean something else. In the eye there is no doubt about the fact, for there the differ- ence of quality remains apparent. If the difference is a fact, there must first be some means of discounting it in practice, whenever confusion might arise from the varying reports. The means consists in taking as a standard the report of that part of the whole organ which is at once most sensitive and most easily moved. For touch this is the hand and especially the finger-tips, the more sensitive tongue being not fit for general work ; for the eye it is the yellow spot about the middle. The hand may truly be called the organ of touch, to which the rest of the skin plays a part like that of the web about a spider : let there be a suggestion of contact anywhere, and straightway the hand can be borne thither, to feel for itself. So in the eye : 60 THE SENSES. no spider darts from its lair in the centre to any part of its web more deftly than the yellow spot turns round, with the swift and easy motion of the eyeball, to catch for itself the images thrown on other parts of the retina. The yellow spot can with like reason be called the organ of sight. Nothing is easier than the movement in either case, and accordingly it is often made when we fancy both hand and eye at rest ; nay, it is very difficult, in touching or looking, not to make some movement of the organs. We come, how- ever, not to need to make an actual movement in order to correct roughly the report of any outlying part. Because the differences in the quality of sensation all over the skin and eye are constant at each part, we learn by long experience to judge well enough for many practical purposes what the standard report would be without moving to get it. We still move hand and eye when we want to be quite sure. Mark now what further happens in touch. The dis- crepancies, though got over as elements of confusion by translation into touch of the hand, remain at the different places constant marks of the respective movements necessary to bring the hand thither. Indirectly, also, two different touches will come to suggest the movement of hand neces- sary to pass from the one place to the other. That is to say, .upon the theory of perception which I am here assuming, each kind of touch comes to be localised directly with reference to touch of the hand, and all indirectly come to be localised with reference to each other. The skin is thus again mapped out, and now in the true sense of a map, with every touch in a certain relative position. And so predominant does this new character become in conscious- ness, that, when now we have touches, we are apt to think of them first as lying apart in their places on the surface of the body, not as they may differ in quality among themselves. The change of character will not seem so wonderful, if we think how in the first months of our lives we were doing little else but feeling about over our bodies with the hands. Its own skin is the first surface that a child comes to know of as spread out in space, and, being itself everywhere sensitive, the skin becomes the direct measure of all surfaces THE SENSES. 61 in contact with it. Accordingly, when it is affected at different points, or over a certain extent, we at once perceive a number of objects, or one continuous object, spread out in a manner corresponding. For a rough and general appre- hension of that sort there need be no actual movement now ; but how much was there not in the past for that to have become possible ! So much for touch. The same does not happen in the eye, because sight itself has to be brought into relation with touch. Sight appears, indeed, to have nothing to do with touch when it opens up far horizons over the face of earth, and even brings within ken the great vault of heaven ; but that is not the work of the eye alone. The ever-changing image on the back of the eye, though it imitates upside down, as far as a tiny flat picture can, all the variety of the great world, gives but a varied suggestion of the experiences to be had from moving up to objects and feeling them — an exact suggestion of objects in a room or on the earth which we can so touch, but a very crude and false suggestion, however beautiful a one, of the star-sown depths of space so utterly beyond our reach. For all its range and delicacy, the eye is but as a servant bringing spoil within the hand's rough grasp ; and only has this compensation, that the mind, so to speak, the master of both, sets the acquisition after all to the servant's account. Wherefore, we speak of simply seeing objects, and we do, in fact, spread over their full dimensions, as apprehended by the moving hand, or imagined upon a corresponding scale, the colour which is the note of the eye's service. Now, because the eye, in spite of this recognition of its work, does not determine what we call the real size, shape, distance, and other such attributes of objects, but only supplies varied marks thereof, we are not to expect that the differences of quality in the sensibility of the retina should among themselves appear in such a new character as that acquired by those of touch. Without ceasing to be mere differences in kind of light and colour, they can each in that character become suggestive signs of such general movements of body as will bring about active contact with the objects. And thus with my eyes simply open and fixed, the mere gradations of optical effect, 62 THE SENSES. as determined by the structure of the retina, suffice to suggest to me such general apprehension of a hall with people in it as I thus get. It becomes a more distinct apprehension when I throw my eyes about and bring part after part of the retinal picture on the spot of clearest vision ; but even so, what the eye does is still only to give a suggestion, though a better-marked one, of the ex- periences I should have in detail, if I were to walk about in the hall and feel over successively the various objects it contains. I have thus tried to bring before you some aspects of a very great subject. How can there be a greater than the Senses, when here we have nothing less than the two worlds of matter and mind brought manifestly together ? Though the subject could only be touched on the surface here and there, I may have given you matter for a good deal of thought. And if there were any need to draw a moral, it might be this, that as the firmest apprehensions and con- victions, like those we have just been considering, may emerge from the slow growth of daily experience, we cannot be too careful, where we have things in our power, what we suffer our daily experience to be. HOW WE COME BY OUE KNOWLEDGE.1 THE old question of the relation of Knowledge and Ex- perience is generally thought to have passed into a new phase in recent years. Nobody now-a-days seriously main- tains the sensationalist position of the eighteenth century. Even those who attach most value to Locke's way of thinking are ready to scout the notion of tabula rasa, and to allow that the old supporters of innate ideas, native intui- tions or whatever else they were called, had a real insight into the nature of knowledge as manifested- by every human mind. There is an element or factor in the individual's knowledge that is there before or, at all events, apart from that which happens to come to him by way of ordinary experience. This other element or factor is now most commonly represented as an inheritance that each human being brings into life with him. The inheritance can perhaps be most definitely conceived in terms of the nervous organisation which, it is practically certain, is involved in all mental goings-on, but it must admit of expression in terms of consciousness also. We are to understand that a human child, being what he is — the offspring of particular parents, of a particular nation, of a particular race, born at a particular stage in the race's development — does know and feel and will otherwise than he would if all or any of these circumstances were different. Nor does this apply only to the general laws and limits of his knowing, feeling and willing : it must apply also to his simplest conscious experience of any sort. An artist's sense of colour or sound will be something different from a costermonger's, and not merely because of a difference in the experience they have had and stored up. Their sensible experience will have been 1 Reprinted, by permission, from the Nineteenth Century, March, 1877. 64 HOW WE COME BY OUR KNOWLEDGE. of intrinsically different quality from the beginning; and the principle of heredity must contain the explanation of such differences, if it does explain the general uniformities to which intelligence appears to be subject in all minds alike. Confining attention, however, on the present occasion, with philosophers in general, to the uniformities of know- ledge— such, for example, as the reference we all make of sensible qualities to a substance or underlying thing in which they inhere, or the conviction we have that every event has been caused — I cannot for my own part doubt that human beings are determined by inherited constitutions (mental or nervous, or mental and nervous) to interpret and order their incidental experience in a certain common fashion. In the absence of a definite mental constitution, which must be inherited because the corresponding nervous organism is inherited, there is, I think, no way of conceiving how human beings come by the knowledge that we seem all to have in normal circumstances ; as, accordingly, when the inheritance is plainly abnormal — for instance, in idiots — the mode or amount of knowledge is clearly different from what it is in other men. At the same time it does not seem possible upon this line to get beyond a general conviction that the way of men's knowing is prescribed for them by ancestral conditions. Or, if the attempt is made to determine the details of our intellectual heritage, it seems impossible to stop and not fall into the notion that original endowment is everything, and a man's life-experience little or nothing, towards the sum of his knowledge. The latest phase of modern philosophic thought, then, becomes hardly distin- guishable from the high speculative doctrine of Leibniz— that in knowledge there is, properly speaking, no acquisition at all, but every mind (or monad) simply develops into activity all the potency within it, not really affected by or affecting any other mind or thing. The notion is of course suicidal ; for how can there be, on the whole, a progressive evolution of all, except there be action and re-action among individuals, as the condition of working up to higher and higher stages of being ? Nevertheless, it is no exaggeration to say that the tendency of recent evolutionism in psychology is to reduce to a minimum, or even crush out, the influence HOW WE COME BY OUE KNOWLEDGE. 65 of incidental experience as a factor in the development of the individual's knowledge. What can happen to the individual in his little life seems to be so mere a trifle by the side of all that has before happened for him through the ages! Once recognise a more or less constant a, priori element in knowledge as coming by way of inheritance, and what is then wanted for the explanation in detail of the uniformity that appears in the knowledge of different men is an ade- quate conception of the actual life-experience. of individuals. It is truly surprising how meagre and artificial — artificial in the sense of coming short of the fulness of natural fact — the conception current among philosophers has been. Sensa- tionalists in particular were concerned to take no narrow view of the case. In point of fact, they so read their famous formula about Sense and Intellect as to throw away a cause that in itself was far from weak. The notion was that children coming into the world had everything to do and find out for themselves. The world was there, and the little creatures, all naked without, and their minds like a sheet of white paper within, were thrown down before it, at once to struggle for bodily existence and to take on mentally what impress they might from surrounding things. If they managed to survive, as somehow they generally did, they were found after a time in possession of a certain amount of knowledge about the world and themselves ; and (most remarkable ! ) this knowledge, though it might be limited, as of course children's knowledge must be expected to be, was yet so definite in each and uniform in all, that it had only to be expressed by a system of signs (which, after long doing with- out them, men had somehow agreed to use) , and the children were turned into sociable creatures with whom it was possible to hold rational converse. Now it is not to be denied that, in working out their theory, the Sensationalists were the first to determine with some exactness the ele- ments of sensible experience involved in many of our most important cognitions, and also those intellectual laws of association under which these elements are ordered or fused (as the case may be). But it cannot be allowed that they gave anything like an adequate analysis of knowledge generally, or, in particular, rendered a likely account of the 5 66 HOW WE COME BY OUR KNOWLEDGE. way in which the swarm of jostling sensations and other strictly subjective experiences settled down and were trans- formed into the coherent and orderly mental representation of boys and girls beginning to communicate with one another and with their parents and friends. The least consideration, indeed, might have revealed the error of the point of view. Children are as little left to work out their knowledge for themselves as to nurture their bodies. If they were left to struggle alone against the world for bodily life, they would assuredly perish. If they were left to find out everything in the way of knowledge by themselves, they might (always supposing their bodily life sustained for the first year or two) come to combine sensible impressions for the guidance of muscular acts ; but they would not be the rational educable creatures that even mudlarks, living the social life, are at the age of three. ' The social life ' — in these words is indicated the grand condition of intellectual development which the older psychologists are far more to be condemned for overlooking, than they can be blamed for not anticipating the notion of heredity that has grown out of the biology of the present century. In the last century, other sciences had not advanced far enough to make scientific biology possible ; and psychology, in as far as it depends on true biological notions, could not but suffer accordingly. But in the last century, as at other times, it was sufficiently plain that children, in being born into the world, are born into society, and are under overpowering social influences, before (if one may so speak) they have any chance of being their proper selves. To say nothing of the bodily tendance they receive —though this is really a fundamental condition of their ever having an intellectual development — let it be considered how determinate their experience is rendered by circumstances or the will of those about them. For long months — such are the conditions of human life — children are confined to the experience of but a few objects ; and even these they become familiar with more through the direct action of others, carrying them about, than through initiative of their own. Apparently a restriction, this first effect of the social relation is, in truth, a potent factor in the development of HOW WE COME BY OUR KNOWLEDGE. 67 knowledge. It supplies the best conditions for that associa- tion and fusion of impressions on the different senses which in some form must unquestionably be got through at the earliest stage of intellectual growth. Being destined to enter into a fabric of general knowledge, the discrete sense- impressions received by children must be elaborated in quite another way, and to quite another extent, than if, as in animals, they were merely to be used for the guidance of immediate action. It is no small thing for children, that the range of their early experience is so narrowed as to give them a chance of becoming perfectly familiar with all the details of it. It is not, however, till a stage after the earliest — though still a very early one — that the effect of social conditions upon the intellectual development of children becomes most marked. Before they are themselves able to speak and be- come full social factors, they begin to have the benefit of the spoken language that holds a society together. What can better help a child to identify as one object a complex of impressions appearing amid ever-varying circumstances, than hearing it always indicated by the sound of the same name ? The first business of children, before they rise to comprehensive knowledge, is to have a definite apprehension of objects in space ; and to this they are helped not least effectively by the fact that there is a current medium of social communication about things, the advantage of which is, strictly speaking, forced upon them. Constraint there is, when one thinks how people are for ever obtruding names upon the child's ear, both when they have occasion to speak among themselves, and when they take occasion (as some are always found ready) to lavish attention upon babies. And though it may well be doubted whether children always relish the outpourings of social tenderness to which they must submit, there can be no question as to the intellectual advantages that, even through suffering, they receive. Their chief end, on emerging from infancy with their little stock of knowledge, is to understand and be understood by others; and, meanwhile, they have entered, without effort of their own, into possession of a store of names adapted to all the exigencies of intelligent intercourse. 68 HOW WE COME BY OUE KNOWLEDGE. But this is only the first, and not the chief, intellectual gain that accrues to children from the existence of ready- made language. Whatever the occasion may have been that first called into play the expressive faculty between man and man, it is beyond dispute that language is required mainly for purposes of general knowledge. The language spoken by a race of men is an accurate index to the grade of intellectual comprehension attained by that race, and the intellectual progress of the race may be traced in the gradual development of its speech. See, then, what comes to the opening mind of the child with the use of his mother-tongue. The words and sentences that fall upon his ear and are soon upon his lips, express not so much his subjective experience, as the common experience of his kind which becomes, as it were, an objective rule or measure, to which his shall conform. Why, for example, does a child have no difficulty about the relation of substance and qualities that has given philosophers so much trouble ? and why do all children understand or seem to understand it alike, what- ever their experience may have been? Why? but because the language put into their mouths, and which they must e'en use, settles the point for them, one and all ; involving, as it does, a metaphysical theory which, whether in itself unexceptionable or not, has been found serviceable through all the generations of men. Or, to take that other great uniformity or law of knowledge which has become so prominent in philosophical speculation since the time of Leibniz and Kant, — why do we all assume that every event must have a 'cause? Let it be granted — though this is, perhaps, doubtful — that all men do arid must always make the assumption. The philosophical difficulty is how any human mind can so far transcend its own limited experience as to make an assertion about all possible experience in all times and places, and it is well known how it has been met by the opposite schools : those at one extreme declaring in various phrase that it is the mind'snature, before all experi- ences, so to [interpret any experience ; and those at the other extreme making what shift they can to show how the conviction springs up with, or is developed from, the indi- vidual's experience. For my part, I can agree with neither. HOW WE COME BY OUR KNOWLEDGE. 69 I cannot go with those who declare that no amount of experi- ence, in any shape or form, can be the ground of such con- viction as we do, in fact, have of universal causation. But I can as little go with the other class of thinkers, when they suppose that a conviction like that is left to the individual to acquire by private experience or effort. Long before children have the least occasion to try what they can do in the way of generalisation upon their incidental experiences, it is sounded in their ears that things in the world are thus and thus ; and that child were indeed a prodigy of pure reason who should pause and gravely determine not to take on the yoke of social opinion till he could prove it, of him- self, well founded. He does — he must — accept what he is told ; and in general he is only too glad to find his own experience in accordance with it. And if to this it be objected that children cannot understand the generalities they hear unless by reason of native principles in their intellectual consciousness, the answer is, that they do not by any means begin by understanding them. This comes only very gradu- ally to the best of us, and to some comes hardly at all. On the whole, then, the description I would give of our early progress in knowledge — and the early progress is decisive of our whole manner of knowing till the end — is something like this : that we use our incidental, by which I mean our natural subjective, experience mainly to decipher and verify the ready-made scheme of knowledge that is given to us en bloc with the words of our mother-tongue. This scheme is the result of the thinking, less or more conscious, and mainly practical, of all the generations of articulately speaking men, passed on with gradual increase from each to each. For the rest, I should be the last to deny, having before asserted, that the part we are intellectually called to play is predetermined for each of us by a native constitution of mind, which, 011 one side, assimilates us in way of think- ing to all other men of our race and time, if also, on another side, it marks us off from all other men and . contains the deepest ground of what is for each of us our proper self. But I desire to express the opinion that there is no explanation of any mind's knowledge from this position, even when account is taken also of all the modes of natural experience noted by 70 HOW WE COME BY OUR KNOWLEDGE. psychologists, unless there is added, over and above, the stupendous influence of social conditions, exercised mainly through language. How far would his native mental con- stitution (whether regarded as an inheritance or not), with all his senses and all his natural activities, carry a child in the direction of knowledge, supposing him to grow up face to face with nature in utter loneliness ? I believe it would need an effort which none of us can so far abstract from the conditions of our knowledge as to be able fully to make — to conceive how insignificant such a creature's knowledge would be. It should be understood that the question raised in this short paper (written originally as a mere thesis for dis- cussion) is a strictly psychological one. The psychologist's concern in knowledge is to show how it is generated in the mind. For this, he must carefully analyse knowledge, as it appears in himself and others, so as to have insight into the matter he would explain, and his work is done when he then shows how knowledge arises in each of us naturally. It is another and very different question — what knowledge is to be held as objectively true or valid for all minds alike. When is my knowledge such that I may claim your assent to it? To answer this question, or, in other words, to determine the conditions of scientific knowledge, belongs to philosophy in general or logic in particular, and remains an imperative task after any amount of psychological inquiry. But the psychological question, within its own limits, is a very real one, and it is indeed the natural, if not the necessary, preliminary to the other. Even as psychological, however, the question is here in various ways narrowed. It is a question referring only to knowledge, to the exclusion of feeling and willing, and to knowledge only as it appears (naturally) with a character of uniformity among different men. The social influence insisted upon does nothing to explain the intellectual idiosyncrasies of each individual : these, if explicable at all in their variety, must be traced to special inheritance (as suggested above) or incidental experience. On the other hand, it is plain that the influence extends beyond intelli- HOW WE COME BY OUB KNOWLEDGE. 71 gence proper to the other great mental phases of feeling and willing. The tendency of men to feel and act alike is indeed even more apparent than to think alike, and assuredly has its explanation not least from the social tie which, from the first, is as a spell upon the individual ; though here again, it may be remarked, there is an ulterior question — whether the feelings and acts naturally excited in men, from association with their fellows, are justifiable in the sight of philosophic reason. The effect of the social relation on the mental development of the individual is, I repeat, a purely natural factor for the psychologist to reckon with ; or, at least, it is so in the first instance, however it may afterwards seem, on evolutionist principles, to carry its justification with it. Yet it has by psychologists generally been quite ignored. The same century that has seen the development of the ' historical sense ' has first begun to comprehend the relation of perfect solidarity subsisting between the individual and society, and for a very good reason. It is, in fact, but one conception differently applied — when the varied life or history of a nation is viewed as growing out of its past, and when the mental life-history of individuals is seen to be determined by the social conditions and traditions into the midst of which they are born. Nor is the doctrine of general organic evolution itself, the latest outcome of thought in the century, aught but a more extended and intenser reading of the same conception. So far as con- cerns the social relation in particular, it may truly be said that to no one thinker or school of thinkers belongs the exclusive credit of having grasped its import for psycho- logical theory. The notion of man as never separable (except by abstraction) from the social organism has emerged at the most different planes of thought, and been suggested by various lines of scientific inquiry. Yet it were almost an injustice not to recognise the peculiar impressiveness with which it was proclaimed by Comte, considering where he stands between those who went before him and those who have come after. If he had much to learn in the matter of psychological analysis from the ' ideo- logists ' whom his soul abhorred, the lesson contained in 72 HOW WE COME BY OUR KNOWLEDGE. his protest against their individualism has in turn been too little or too slowly regarded. It is remarkable how much of the celebrated English work of the present century in philosophy or psychology has continued to be done from the individualistic point of view. Mill's theory of know- ledge, for example, greatly as it is in advance of Hume's as a serious constructive effort, is yet only such a doctrine (whether of everyday experience or of organised science) as Hume himself might have set forth a hundred years ago, had he been really minded, as he at first professed, to work towards a positive theory, instead of spending his strength in pricking the bubbles blown by dogmatic metaphysicians. Professor Bain's psychological researches have been almost wholly analytic, in the manner of Hartley's : of extreme importance as such — witness, in regard to the very question of tbe sources of knowledge, his discovery (for it was hardly less) of the element of muscular activity in objective per- ception— yet merely adding to the list of formal factors involved in a complete psychological construction.1 Mr. Spencer, it is true, has always looked beyond the individual for an explanation of the facts of mental life, intellectual or other, but he has concentrated his energy as a psychologist on the elucidation of the principle of heredity. It is only in more recent psychological works, like Mr. Lewes's, or as yet in less systematic essays and general literature, that the social influence of man on man is forcing its way to recogni- tion as a factor second to none in the actual process of mental development. A few words may be added, before closing, on one question that suggests itself. How does the recognition of social influence in the development of the individual's knowledge affect the position now commonly called Experientialism ? It is here conceded, as a matter of fact, that no one's know- ledge is explicable from his individual experience. Although, of course, there is a sense in which all that a man knows 1 It should be noted, however, that in one of his most characteristic researches— his doctrine of the growth of Volition — Professor Bain has by no means confined himself to the analytic attitude ; and here it is interesting to observe that he distinctly posits the social influence as a factor in the development, when showing how volition is ' extended ' by imitation. HOW WE COME BY OUR KNOWLEDGE. 73 must have been experienced by himself, it is nevermore true that it depends upon the individual as such, either actively or passively, what his knowledge shall be. Doubly, as we have seen, is he beholden to his fellows. He comes into the world what he is, even on the most strictly personal side, through his ancestors having been what they were and done and borne what they did in their time. And no sooner is he in the world but he enters upon the heritage of social traditions in the speech and ways of his kind. Not his to wrestle by himself with a confused and perplex- ing experience, if haply he may attain to some rude con- struction of a world not too unlike that of other struggling human atoms. His task at the first is but to accommodate his experience to well-approved working rules supplied from without, which more than anticipate his wants ; nor is it other to the last, unless he be one of the few in each generation who, having assimilated existing knowledge, are moved to enlarge the intellectual horizon — to pluck up the stakes where they found them and plant them farther out for others slowly to work up to. The experientialist doctrine thus appears wholly at fault if it means (as it has often been taken by supporters and opponents alike to mean) that all intellection was first sensation in the individual, or even (in a more refined form) that general knowledge is elaborated afresh by each of us from our own experience. Neither position can be main- tained in psychology. And yet it is notorious that exactly those who now urge the presence of such a priori and ab exteriori factors in the individual's knowledge as are here contended for, and are not the least forward to make light of incidental experience, sot most store by the teaching of the older experientialists, and would affiliate their doctrine upon the work, such as it was, of Locke and Hume. For this there is a deeper reason than is commonly assigned. It is common to say that inherited aptitudes are, after all, only a slower result of experience, developed in the race instead of the individual ; and the like may be said still more evidently of the social tradition deposited in the growing languages of mankind. The real bond, however, between experientialists at the present day and those of an earlier 74 HOW WE COME BY OUR KNOWLEDGE. time is that both declare experience to be the test or criterion of general knowledge, let its origin for the individual be what it may. Experientialism is, in short, a philosophical or logical theory, not a psychological one. The fact that the pioneers of scientific psychology in the last century were experientialists in their philosophy is not without signi- ficance, but the two spheres of inquiry should not therefore be confounded. One may be Lockian in the spirit of one's general thinking, without allowing that Locke or his im- mediate successors read aright the facts of mental develop- ment. It is as a philosophical theory that experientialism goes on steadily gaining ground. ANALOGY.1 ANALOGY is the name in logic for a mode of real or material inference, proceeding upon the resemblance between parti- culars : speaking generally, it is that process whereby, from the known agreement of two or more things in certain respects, we infer agreement in some other point known to be present in one or more, but not known to be present in the other or others. It was signalised already by Aris- totle under the different name of Example (irapd^e^^a), the word Analogy (ava\o but which, in view'of these misunder- standings, I would now accentuate. It is that geometers should abandon the use of the logical terms converse and obverse for extralogical relations. The terms inverse and reciprocal, used by M. Delboeuf in his Prolegomenes philosophiques de la Geometric (Liege, 1860), p. 88, are equally significant, while they lead to no confusion with the purely logical processes that should be familiar to every scientific reasoner — Obver- sion and Conversion as well as Contraposition. 10 JEVONS'S FORMAL LOGIC.1 MB. JEVONS'S work, The Principles of Science,2 since its appearance more than two years ago, has not received anything like the amount of attention it deserves. That such a book should have remained so long unnoticed by the greater reviews that could devote sufficient space to the critical appreciation of its contents, is indeed a signal proof of the need for a special philosophical journal. An attempt will be made in these pages to examine it with due care. It is a work of much excellence, yet also, as it seems to the present writer, open to exception in many ways. Mr. Jevons begins by expounding a theory of Formal Logic, deductive and inductive. Upon this basis he pro- ceeds to explain the science of Quantity, especially Number, as an outgrowth from pure logic, and in the same relation deals particularly with the theory of Probability, of which he finds the scientific — or, as he commonly calls it, the inductive — investigation of Nature to be a mere applica- tion. He next turns aside to set forth the various Methods of Measurement employed in quantitative research. Then follows in full detail his doctrine of Inductive Investigation, with a subsidiary treatment of Generalisation, Analogy, &c., and a preliminary handling of Classification, to be carried out in a future work. Meanwhile the present work reaches its term with some general reflexions on the results and limits of Scientific Method. The Methods, rather than the Principles, of Science would perhaps be a more appropriate title for the book as it stands. Systematic investigation of principles in any philosophical sense of the word there is none. On the other hand, the exposition of methods employed in the 1 Mind, i. 206. 2 The Principle* of Science : A Treatise on Logic and Scientific Method, by W. STANLEY JEVONS, M.A., F.E.S. 2 vols. 1874. Macmillan & Co. JEVONS'S FORMAL LOGIC. 147 actual investigation of nature is most elaborate and alto- gether admirable. No such exposition existed before ; and, as far as the present writer can judge or can learn from the judgment of competent authorities, the accuracy of Mr. Jevons's acquaintance with the most varied departments of science is singularly great. As a methodologist he has fairly outstripped predecessors as great as Herschel, Whewell and Mill. If the book really corresponded to its title, Mr. Jevons could hardly have passed so lightly over the question, which he does not omit to raise, concerning those undoubted principles of knowledge commonly called the Laws of Thought. The question is whether these are subjective or objective, and Mr. Jevons is of opinion — an opinion in which he does not stand alone — that they are at once sub- jective and objective. One wishes, however, that he had given some reasons for his view, and not, in a book dealing ex- pressly with the Principles of Science, contented himself with the bare statement that he is "inclined to regard them as true both in the nature of thought and things " (i. p. 9). Everywhere, indeed, he appears least at ease when he touches on questions properly philosophical ; nor is he satisfactory in his psychological references, as on pp. 4, 5, where he cannot commit himself to a statement without an accompaniment of "probably," "almost," or "hardly". Eeservations are often very much in place, but there are fundamental questions on which it is proper to make up one's mind. Judged by his book, Mr. Jevons does not equal either Whewell or Mill in philosophical grasp. The present article will treat only of the first part of the work, l in which the author following in the track of recent logicians seeks to recast the traditional doctrine of Formal Logic, by propounding a new principle of reasoning and, in furtherance of its application, devising an appropriate system of symbolic expression for logical propositions. Since the doctrine of the Quantification of the Predicate JEven this to the exclusion of the last chapter in it, dealing with formal Induction, which will best be considered in connexion with Mr. Jevons's general doctrine of inductive inference. 148 JEVONS'S FORMAL LOGIC. was first enunciated in this country by Mr. George Ben- tham in 1827, and brought into vogue later by Hamilton, various attempts have been made to set aside the older doctrine of proposition and inference which originated with Aristotle ; and of late years no one has laboured so per- sistently at the double work of demolition and reconstruc- tion as Mr. Jevons. In two previous essays, Pure Logic (1864), and Substitution of Similars (1869), also in a variety of special papers, he has felt his way towards the doctrine which he now propounds in a form that, if not final, yet appears to him sufficiently developed to supersede at once all other modern doctrines and that ancient one against which they were levelled. It is advanced as embodying all the anti- Aristotelian import of the newer theories ; at the same time, as systematised or organised beyond any of them ; and yet withal as perfectly simple in principle and details when compared with the greatest among them —the very complex and long-drawn system of the late Prof. Boole. Nor does Mr. Jevons at all exaggerate the merits of his doctrine in relation to his compeers. He is superior to Boole not only in the simplicity and direct- ness of his logical processes but ajso in his conception of the relation of logic to mathematics. His own doctrine of Number is not in all respects satisfactory, as may on another occasion be shown, but his arguments (pp. 173, 4, et alib,} against Boole's notion of logic as a special kind of algebra, are excellent and decisive. We may proceed then to consider Mr. Jevons's doctrine as the best outcome of the modern revolt against the Aristotelian system, sure that nothing has been urged in opposition more strongly than he urges it. Mr. Jevons's Introduction may be described as a summary plea for a statement of the reasoning process which shall be strictly universal and not, " like the ancient syllogism," cover "but a small and not even the most important part" of the whole extent of logical arguments. The universal principle (of "Substitution") suggested is in these words: " So far as there exists sameness, identity or likeness, what is true of one thing will be true of the other ". Here there is evidently implied an expression of logical propositions in JEVONS'S FOEMAL LOGIC. 149 the form of equations, and accordingly a general justifica- tion is offered for such a mode of expression, while an appropriate system of symbols is indicated. A chapter on Terms is then placed first according to the usage of logicians, and Mr. Jevons has both amendments and advances to pro- pose upon the common doctrine, besides fixing more exactly the nature and conditions of his symbolical expression of the terminal elements of propositions. The next chapter deals with Propositions themselves, and contains all the express arguments the author has to offer for putting them into the equational form. He is now in a position to treat of Direct Deduction, which consists in an application of his principle of Substitution to the terms of (equational) propositions under the first law of thought (Identity), and here he seeks to show how small a part of all deductive reasoning is represented by the forms of Syllogism, also how imperfect is the representation. There remains the process of Indirect Deduction, consisting in the practice of Substitution under the laws of Contradiction and Ex- cluded Middle (Duality) as well as Identity ; this has however to be prefaced by a consideration of Disjunctive Propositions, since the alternative relation (either-or) is employed in the expression of any logical notion in terms of another according to the law of Duality. The Indirect Method of Inference is introduced at first as a merely sup- plementary process, to be resorted to as the means of prov- ing that a thing cannot be anything else than a particular thing when it cannot be directly proved to be that thing ; but it shows itself so powerful that it ends by swallowing up Direct Deduction and remaining alone in the field as the truly universal process of reasoning. It proves to be able to furnish a complete solution of the universal problem : Given any number of logical premisses or conditions, re- quired the description of any class of objects or any term as governed by those conditions ; and being a process that follows a fixed unalterable course in all cases, it can be shortened and facilitated by a number of contrivances, on which Mr. Jevons has spent much inventive power. The most remarkable is his famous logical machine, which in a most ingenious fashion does unerringly perform the work 150 JEVONS'S FOEMAL LOGIC. of pure logical combination, the mind by a conscious process having first brought the premisses given into a definite symbolic form and again at the close having to interpret the results mechanically attained. There is some difficulty in assigning the precise ictte-mbre of the system. Mr. Jevons does not say whether reasoning is what he describes it — a process of substitution — because propositions ultimately understood are equations, or whether it is the substitutive character of reasoning that necessitates the adoption in logic of the equational form. On the whole the latter seems to be his view, since he allows that proposi- tions may be expressed otherwise ; but in any case the two positions are involved with each other in his mind, and it is evident from the beginning that it will be a main part of his task to develop a doctrine of Proposition suited to the prin- ciple of Substitution. Hence the rough outline of such a doctrine advanced in the Introduction ; where he maintains that the analogy between the relation of subject and pre- dicate in logical propositions and the relation of the two terms in mathematical equations justifies the use of the mathematical sign = for the logical copula. At this stage he does not urge that the sign ought always to be so employed, for he even speaks (p. 20) of equality as but one of many relations that may subsist between logical terms, and from this point of view gives to the general formula of logical inference the new expression : "In what- ever relation a thing stands to a second thing, in the same relation it stands to the like or equivalent of that second thing". Here also, however, one equation is presumed before the reasoning, as understood by Mr. Jevons, can proceed, and the critical question remains how to determine equival- ence in logical propositions generally. That it can be done is clear to Mr. Jevons, when he asserts shortly afterwards (p. 29) that " every proposition expresses the resemblance or difference of the things denoted by its terms " ; but this of course is the very point to be proved, and the mere asser- tion decides nothing. The chapter on Terms may be lightly passed over. Mr. Jevons, in as far as he adopts the common distinctions (general-singular, abstract-concrete, collective- distributive JEVONS'S FORMAL LOGIC. 151 and the like) does not add anything of importance to the determination of their character, while some of his state- ments are decidedly loose. In particular he confuses the singular and the proper name when he charges logicians with erroneously asserting that singular terms are devoid of meaning in intension: Mill, whom he points at, never says any such thing of singulars — says of many singulars quite the reverse — and in denying connotation to proper names is surely correct. Mr. Jevons himself would set up a new class of terms under the name substantial, which he finds, oddly enough, to partake of the nature both of abstracts and concretes. Gold, for instance, is a concrete substance, yet it has a uniformity or unity of structure — being gold with all its qualities in every part of it — which allies it with abstracts like redness ; for redness, according to Mr. Jevons (p. 34), " so far as it is redness merely, is one and the same everywhere, and possesses absolute one- ness or unity ". Logicians, he complains, have taken very little notice of such terms. But why should they take any notice of a distinction that is wholly material or extra- logical ? Gold is a concrete, so is water and so is lion. What matters it to the logician that you always break up gold, being an elementary substance, into parts of identical character, but not always water, because water is a com- pound, and never lion, because lion is an organism ? If Mr. Jevons will embark upon such distinctions, he will not soon come to the end of them. This one, too, is not happily named. Are not lion and water also substantial? The fault extends to Mr. Jevons's account of collective terms, as the reader may see on p. 35. What remains of the chapter has its importance in relation to the symbolic expression of terms in propositions, and to the central doctrine of Proposition let us pass. It is now Mr. Jevons's express object to show that all forms of proposition " admit the application of the one same principle of inference that what is true of one thing or circumstance is true of the like or same" (p. 43), and this, we understand, amounts with him to proving that all propositions may be expressed as equations. Propositions, he begins by saying, may assert an identity of time, space, 152 JEVONS'S FOEMAL LOGIC. manner, degree or any other circumstance in which things may agree or differ, and in support he cites a number of instances where the notion of sameness or equality is ex- pressed or more or less distinctly implied in the predicate. No doubt, there is a sense in which such propositions assert identity, but they make nothing for the general thesis that identity of some kind is what all propositions express. Proceeding however to maintain the thesis in regard to all propositions involving ''notions of quality" (which is as much as to say all logical propositions whatever),1 he finds at once that "the most important class" consists of asser- tions which may be called " Simple Identities," represented by the formula A = B. Let us look at these more closely. As illustrations of Simple Identities, Mr. Jevons adduces two cases of similar sensible qualities, one or two cases of verbal synonyms, some cases of propositions with singular names as subjects, some cases of definitions, one case of a number of objects brought together into a collective expres- sion, some geometrical equations (e.g., Equilateral triangles = Equiangular triangles), and some expressions concerning uniform and exclusive co-existence of qualities (e.y., Crys- tals of cubical system = Crystals incapable of double refrac- tion). He mixes all these up together as if they were of equal importance logically ; but, while some of them are irrelevant, being propositions of the kind noted before in which the identity or similarity asserted is really part of the predicate, others, it is plain, are propositions only by cour- tesy, being either of no logical importance, because they are assertions about mere names or about singular things under proper (meaningless) names, or logically important as de- finitions not as propositions. In short, none of the illustra- tions are of any real account for Mr. Jevons's argument except those falling under the last two heads of the fore- 1 Mr. Jevons speaks here (p. 44) of " confining attention " to the pro- positions thus described, and leaving over propositions concerned with number and magnitude. In fact he leaves none over, for propositions about quantity, which are those he has in view, do in respect of logical form involve what he calls " notions of quality " as much as any others (else, how should logic be the truly fundamental science ?) ; and accord- ingly he does not scruple (p. 46) to refer to such among others in spite of any previous exclusion. JEVONS'S FORMAL LOGIC. 153 going list. Keal or synthetic propositions like those involved in the equations cited or in another often mentioned by Mr. Jevons, Exogens = Dicotyledons, are alone worthy of consideration. Let Mr. Jevons claim all the others as simple identities, similarities or what not as he will, and make formal equations out of every one of them. The question remains whether a real proposition about equila- teral triangles or exogens can be legitimately put into the form of an equation with the mark = for copula, or whether equations like those quoted represent the propositions with which logic has to deal. In point of fact, as Mr. Jevons is forward to allow, logic has many propositions to deal with that are anything but Simple Identities, e.g., Mammals are vertebrates; and pro- positions of this type, in which the subject is commonly said to be included within the predicate, were taken by Aristotle as fundamental. For this act and his supposed consequent neglect of Simple Identities, the venerable father of logic has many reproaches showered on him (pp. 46, 48, 50, &c.), but Mr. Jevoiis should look into the Prior, to say nothing of the Posterior, Analytics and see if Aristotle was as oblivious as he supposes. Choosing to take his Simple Identities as fundamental, Mr. Jevons has to bring the other class into relation with these, and very curious it is to watch his pro- cedure. He had pronounced Simple Identities "the most important class," "all-important," &c., and one would ex- pect the others to be less important. From the first, how- ever, he is forced to call them " an almost equally important kind" (p. 47), while later on they prove to include "the great mass of scientific truths " and " the most common of inductive inferences " (p. 149) : they also enter into infer- ences "almost more frequently" than any others (p. 66). He observes besides that "in ordinary language the verb is or are expresses mere inclusion more often than not " (p. 48), an assertion which, though far from correct — for in truth the copula by itself means neither inclusion nor identity — affords, one would think, with the other state- ments as to the scientific importance of this class of propositions, a very sufficient justification for Aristotle's selection of them as fundamental. Mr. Jevons notwith- 154 JEVONS'S FORMAL LOGIC. standing will have identities made of them in subordina- tion to his grand class (how grand we have seen !) of Simple Identities, and asserts, like others before him, that, though in the proposition, Mammalians are vertebrates, the terms are not simply identical, still there is identity between the mammalians and part of the vertebrates. Let the rela- tion then be called a " Partial Identity". Quantifiers of the predicate insert the word some, and Boole uses a special symbol V, to mark the partial character of the identity : Mr. Jevons prefers another mode of symbolism. Mamma- lians (A) are identical with all vertebrates (B) that are mammalians (A): hence we may write A = AB, a form, he maintains, which at once fully expresses the whole content of the proposition and brings it into line with the fundamental class of Simple Identities. Add that, in order to get uniformity of copula (to be marked by the sign of equality), he does away with the distinction of affirmative and negative propositions, after the manner of Hobbes and others, by attaching the mark of negation to the predicate, while, after De Morgan, he chooses italics for the symbolic expression of negative terms (a for not-A), and we have before us perhaps all that is necessary for the understanding of Mr. Jevons's expression of propositions.1 But we have still to learn the exact meaning of such a Simple Identity as Exogens = Dicotyledons. It means, says Mr. Jevons on p. 19, that "the group of objects denoted by the one term is identical with that denoted by the other in everything except the name ". The identity, he further remarks, " may sometimes arise from the mere imposition of names, but it may also arise from the deepest laws of the constitution of nature". Here and in the words which follow on p. 20, Mr. Jevons clearly enough indicates the difference of verbal and real propositions which in his illus- 1 He distinguishes, it is true, another " highly important class of pro- positions " (p. 51) under the name of .Limited Identities, with the formula AB = AC, meaning: "Within the sphere of the class of things A, all the B's are all the C's ; " but this class we may neglect. I remark only in passing that the example given by Mr. Jevons— Plants that are large are the plants that are devoid of locomotive power — though one sees how it miyht be represented by the formula, can hardly be so represented consistently with his symbolic expression of the other classes. JEVONS'S FORMAL LOGIC. 155 tration of Simple Identities he confuses or ignores ; but this by the way. To return to the example, he makes still another remark (p. 19), that it is " a logical identity express- ing a profound truth concerning the character of vegetables ". There is here perhaps a faint suggestion that somehow the qualities connoted by the two terms are identical, but Mr. Jevons's view thus far plainly is that the only identity in the case is identity of objects denoted : the qualities connoted by the terms are indeed expressly different. So elsewhere (p. 58) he tells us pointedly that the equation means "that every individual .falling under one name falls equally under the other". He adds, it is true, an alternative reading — " That the qualities which belong to all exogens are the same as those which belong to all dicotyledons " — which seems at variance with the other ; but, rightly understood or given, it comes to the same thing. As it stands, the reading is of course erroneous if it means, as the words most naturally suggest, that the exogenous quality and the dicotyledonous quality are identical, not to say that it would, if valid, turn the proposition into one purely verbal. The true reading, however, which Mr. Jevons must be supposed to have in view is — that the qualities which belong to all exogens as such and the qualities which belong to all dico- tyledons as such are always found together in the same objects. Thus we are brought back to identity of objects. And it may be freely granted that, where there is such thoroughgoing identity of the objects denoted by two names of different connotation, the substitution of one for the other is in this sense admissible that precisely the same objects will always be pointed at by either. It is also, no doubt, possible to mark this particular fact by the use of the mathematical sign for equality. Next as to Partial Identities. It is equally true, in the expression Mammalians = Mammalian Vertebrates, that the same objects are indicated or denoted by the two terms of the equation ; and the substitution in any case of the one for the other will always be admissible in the sense that precisely the same objects will continue to be meant under the more complex as under the simpler description. So far there is no more objection to the equational form here than 156 JEVONS'S FORMAL LOGIC. before. But how then is the identity, what Mr. Jevons here •calls it, partial / It is as complete as in the class of Simple Identities : indeed, if it were not so, it would be impossible to use the sign of equality or to practise that process of sub- stitution (reasoning) for the sake of which the equational •expression is adopted. What Mr. Jevons means by calling it partial is of course plain enough : he is thinking of the terms, not as they appear after manipulation in the equation, but as they appeared in the original proposition, where the terms are not simply interchangeable — do not indicate pre- cisely the same objects — but are interchangeable only under certain conditions laid down in the doctrine of logical Con- version. In short, the equation in this case appears as a highly artificial expression for the natural proposition — artificial in the literal sense that work has had to be done upon the proposition to bring it into the new form, and, if it is called a partial. Identity, artificial also in the other sense of being a hybrid form — neither proposition nor equation. Mr. Jevons, it may here be added, claims as the first fruit of his theory — that it supersedes the whole doctrine of Con- version (p. 55) ; and we are now in a position to judge with what reason. If you take a proposition, Mammalians are vertebrates, and first carefully inquire what limits must be put upon the interchange of its terms, and then express those limits by a symbol, and finally, as you then may, express the whole as an equation, the very meaning of which is that it holds either way, — no doubt, you need the doctrine of Conversion no more ; but you have assumed and used it in the preliminary process all the same. In truth, you have at the end not only surmounted Conversion : you have also got rid of Subject and Predicate — which means, if it means anything, that in attaining Equation you have abolished Proposition. Perhaps it is well so, but at least let it be understood, and let us talk no more in logic of " propositions ". Mr. Jevons, however, is perfectly aware that his expres- sion for the common logical proposition may seem " artificial and complicated," and he gives due notice that it is on "general grounds" he contends for reducing every kind of proposition to the form of an identity (p. 50). . These JEVONS'S FORMAL LOGIC. 157 grounds, in character mainly practical, we shall presently examine, but the prior theoretic question, least thought of by Mr. Jevons, must first be once for all considered. The question is whether the logician, dealing with Thought, must start from Equations of the type A = B or from Pro- positions of the type A is B. If from Equations, they will be of the type of Mr. Jevons's Simple Identities, because all others, for example Partial Identities, are intelligible only as approximations to the simple type, and, but for the existence of the class represented by A = B, it would hardly occur to anybody to express the proposition A is B in the form of an equation (A = AB or otherwise). If from Pro- positions, they will be of the common type A is B, because no simpler conjunction of subject and predicate can be assigned. The question then resolves itself into another : Which of the two expressions is really the simpler and truly represents the fundamental act of Thought ? Mr. Jevons can only be understood as maintaining that it is the expression A = B. This appears from the whole course of his exposition, from his oft-repeated attacks on Aristotle (who took precisely the opposite view), and very expressly in a passage (p. 135) where he stigmatises as. "the most serious error" of De Morgan's logic his holding "that because the proposition All A's are all B's (A = B) was but another expression for the two propositions All A's. are B's and All B's are A's it must be a composite and not really an elementary form of proposition ". That is to say : the expression A = B is an elementary form of proposition and, for the reason just stated, the elementary form. But Mr. Jevons nowhere denies, nay himself repeatedly asserts, that the one expression A = B may be resolved into, or, what is the same thing, includes the two expressions A = AB (A is B) and B = BA (B is A) ; while his ingenious logical machine positively refuses to entertain the Simple Identity except in this double form. How can he then deny that the proposi- tion A is B is in the truest sense simpler and more funda- mental than the manifestly complex expression A = B ; that this latter is not a logical proposition at all but a shorthand expression for two logical propositions which cannot further be resolved ? All that he says in reply to the dumb protest. 158 JEVONS'S FORMAL LOGIC. of his machine is that he does not think the "remarkable fact " of its taking in only the common logical proposition does really militate against the simplicity of his equational form A = B (p. 129). All the argument that he urges for the simplicity of the form is given at p. 71, where he asserts it to be more " simple and general " than either A is B or B is A, apparently because it follows from the two taken to- gether and contains as much information as both of them ! That seems a strange inversion of the meaning of generality and simplicity ; and, for my part, I cannot understand how, in point of theory, any question remains. The question of the practical utility of equational or propositional expression is a different one and must be separately considered ; but, in point of theory, it surely seems final to say that, if a form can be resolved into two other forms and each of these cannot further be resolved either back again into the first or into anything simpler, we have got hold of elements or what may pass for such. The proposition A is B is such an elementary form in logic and expresses an act of thought as judgment than which none simpler can be assigned. The expression A = B (all A is all B) is not elementary, because it stands for two distinct judgments at once. From the theoretic point of view there is, moreover, another fundamental objection to the use in logic of the sign for equality. The only sense in which it can be under- stood, when applied to logical propositions, is, as we saw, to represent identity of the objects denoted by the terms : if understood of the attributes connoted by the terms, it does not at all express the true import of a real (synthetic) proposition. But it is precisely by their attributes — the aspect which cannot be expressed in equational form — that we think of things or bring them into logical relation, as Mr. Jevons allows (p. 58) when he says in language of his own (which I do not wholly adopt) that " there are many reasons for believing that the intensive or qualitative form of reasoning is the primary or fundamental one". I hold, therefore, on this ground also, that the equational form is theoretically inadmissible in logic. If, notwithstanding, Mr. Jevons is able, as we shall see, to work out with it a con- sistent doctrine of reasoning, this is due to the fact that JEVONS'S FORMAL LOGIC. 159 connotation and denotation stand in a definite relation ; and the doctrine may have its practical justification. But the theoretic difficulty remains. We may now proceed to consider the grounds, mainly practical, upon which Mr. Jevons himself rests the credit of his doctrine with its equational base. General harmony, he contends, is established among all parts of reasoning (p. 50), and thereby a solution of the general logical pro- blem is rendered possible (p. 105). He speaks also of Aristotle destroying "the deep analogies which bind to- gether logical and mathematical reasoning" (p. 48), and by implication claims that his doctrine reveals them. This second point may first be shortly disposed of. Save with the practical view of securing for logic the full use of algebraical processes, it is not clear why it should be a special object to establish analogies between logical and "mathematical" reasoning; for, if logic is the fundamental science, as Mr. Jevons triumphantly argues against Boole, there seems no meaning in seeking to do more than deter- mine the exact logical import of mathematical, as of other scientific processes. It is clear, however, that the supposed practical advantage cannot be secured without subordinat- ing logic to algebra. Now could there be a more effective way of throwing doubt on its fundamental character than to find that specially mathematical processes are applicable in logic ? Even the use of the single sign for equality is fraught with peril in this respect, more especially as upon it depend any other "deep analogies" there may be. Whether there be analogy or not between the sign in mathematics and the copula in logic, the sign is a mathe- matical one and cannot be used in logic without giving to mathematics from which it is drawn a prerogative character. Mr. Jevons accordingly, for all his opposition to Boole, is not proof against the temptation to settle logical questions off-hand upon grounds of mathematical analogy ; as where, for example, he urges against the doctrine of logical Con- version the usage of the mathematician who " would not think it worth mention that if x — y then also y = x" (p. 56) ; obviously begging the very point in question as to the iden- tity of subject and predicate with the terms of an algebraical 160 JEVONS'S FORMAL LOGIC. equation. So much for the fundamental analogy. For the rest let us hear Mr. Jevons himself on the other side of the question. At p. 81, he tells us that originally he agreed with Boole in using the sign + for the conjunction or as marking logical alternation, but agrees no longer because the analogy between mathematical addition and logical alterna- tion is " of a very partial character ". Then he adds " that there is such profound difference between a logical and a mathematical term as should prevent our uniting them by the same symbol". Now I do not suppose that in this last statement, general as the wording is, Mr. Jevons is thinking of anything but the particular symbol + which he is anxious to extrude from logic ; but I do not see why it does not tell with equal force against the use of the symbol = , the true fount and origin of the evil against which he finds it thus necessary to protest. In short, we have not yet got from Mr. Jevons a practical, any more than a theoretic, reason for the introduction of the fundamental symbol, and we do find him uttering a most impressive warning against a practical danger which it most naturally entails. The justification of the first step we must therefore look for elsewhere, namely, in that perfectly harmonious doctrine of reasoning which, we are led to suppose, can thus and not otherwise be developed. The mode of reasoning first considered by Mr. Jevons, Direct Deduction, consists, as before mentioned, in Substitu- tion practised under the one law of Identity, or, in other words, upon the premisses as given. Here, neglecting minor matters, let us at once note the points which he seeks to make against Syllogism, to the advantage of his own method. The syllogistic doctrine, he says, (1) takes no account of inferences involving Simple Identities either ex- clusively or along with Partials, and (2), where it is applic- able, namely to Partial Identities, it draws an incomplete conclusion (p. 69), nay, sometimes even a dubious one (p. 72), while it does its work always in a clumsy incomprehensive way (p. 67), and moreover has to be supplemented by elabor- ate rules for the avoidance of Fallacies (p. 75). These two last heads of the second charge cannot be met without com- paring in detail Mr. Jevons's plan for obviating the special JEVONS'S FORMAL LOGIC. 161 doctrines of Figure and Mood and of Fallacies, and I will merely say that the attentive reader will find the simplifica- tion much more apparent than real.1 The main charges against Syllogism one is bound to meet. For this it is im- portant to note what Mr. Jevons means by logical conclusion or Inference. He finds it not easy to say, but at last (p. 137) commits himself to the assertion that "logical change may perhaps best be described as consisting in the determination of a relation between certain classes of objects from a relation between certain other classes". Now turn to the "infer- ences" as he calls them, which he charges "the ancient syllogistic system " with overlooking. Prominent among them are assertions of "equivalency of words," interchange- ability of definitions and the like (pp. 62-5). . But these are no inferences at all, either as understood by any serious up- holder of syllogism, or, as we have just seen, by Mr. Jevons himself. It is true that amid such utterly trivial cases of verbal re-expression Mr. Jevons cites some cases of true (formal) inference from real compound assertions in the form of equations (see in particular one at the head of p. 64), but Aristotle, as already suggested, did by no means overlook such, though very rightly he did not make them fundamental in his system. As for the charge of incompleteness brought against the common syllogistic conclusion, let it be given in Mr. Jevons's own words: "From Sodium is a metal and Metals conduct electricity, we inferred that Sodium = Sodium metal conducting electricity, whereas the old logic simply concludes that Sodium conducts electricity" (p. 69). I ask which form of the conclusion best corresponds with Mr. Jevons's own definition of logical change or inference. There is some meaning in calling the common syllogistic conclusion an inference (formal) : Mr. Jevons's so-called conclusion is a summing-up — a compendious description. Lastly, the still graver charge insinuated that the syllogism reader will also find some wholly misdirected argument on p. 76, where Mr. Jevons contests the universality of the rule that two negative premisses yield no conclusion. The example he urges by way of excep- tion is no exception. There are four terms in the example, and thus no syllogism, if the premisses are taken as negative propositions ; while the minor premiss is an affirmative proposition, if the terms are made of the requisite number three. 11 162 JEVONS'S FOEMAL LOGIC. sometimes yields a conclusion that is open to positive misin- terpretation (p. 72) has only to be looked at to fall away. From the two assertions, Potassium is a metal and Potas- sium floats on water, the syllogistic conclusion is that Some metal floats on water. Mr. Jevons objects that some metal (or, as he writes it, metals) is here liable to be understood too widely, when in fact all you can be sure of from the premisses is that the one metal potassium floats. But he ought to remember that some in logic means not-none and that only. How can it then be understood here too widely ? In what respect is the conclusion not perfectly exact ? His own expression Potassium metal = Potassium floating on water, if it can seriously be called a conclusion at all, is not a whit more safe against misinterpretation. Because it does not prove that gold will not float, anybody who cares may stoutly maintain that gold perhaps may. Logic is not meant nor has any power to bar out wilful irrelevancies. So much for Direct Deduction. It is however in the In- direct Method of Inference that Mr. Jevons's doctrine culmi- nates, affording that solution of the general problem of logic which is the true mark of its superiority. Unfortunately it is just at this stage that it becomes impossible to give in brief form a satisfactory statement of the doctrine as a basis for criticism : Mr. Jevons himself without wasting words takes not a few pages to expound the method fully. The method reposes ultimately on the fact that, under the law of Excluded Middle, anything in logic may be expressed in terms of anything else — in the form, namely, of the dis- junctive propositions A is either B or not-B. Conceive then a set of premisses involving several terms (two, three, four, &c.) : what possible alternative combinations of the terms there are, without reference to the premisses, may always be fixedly determined, and what particular combina- tions are possible with reference to, or consistently with, the premisses may then be determined by a process of substitution followed by an application of the law of Con- tradiction. Those to whom this statement is obscure must go to the book itself, where they will see the whole method not only clearly set forth and copiously illustrated, but gradually brought into such a shape that the machine JEVONS'S FOEMAL LOGIC. 1(53 devised by Mr. Jevons does the purely logical part of the whole process. It should in any case be evident why Mr. Jevons lays particular stress upon t'he relation of Disjunction or Alter- nation and devotes a special chapter to it, though some may wonder why in a theory of pure logic he takes no express account of the relation of Eeason and Consequent in hypothetical propositions, upon which disjunctives have hitherto generally been supposed to depend. As it stands, the chapter on Disjunctive Propositions contains much that is of value. Mr. Jevons argues strongly for the view main- tained by some logicians (Whately, Maiisel, Mill, &c.), against others (Hamilton, Boole, &c.), that either-or- does not mean if the one. then not the other but only if not the one then the other. Without adopting all his arguments (for here as elsewhere he does not distinguish sufficiently between mere verbal expression and real thought) one can agree with his conclusion so far as to say that logical alternation does not universally mean more than is conveyed by the second of the two hypothetical expressions. It is not clear, how- ever, why Mr. Jevons should argue so elaborately for his conclusion. The alternation he has in view for the develop- ment of logical terms under the law of Excluded Middle, as in A is either B or not-B, is one where the alternatives are mutually exclusive ; and in no other sense of Alternation can he describe it (which he does at the beginning of the chapter) as a process equal to that otherwise known as logical Division — the inverse process to Generalisation.1 All this, however, by the way. What, then, shall be said of the Indirect Method itself? Undoubtedly it does accomplish all that Mr. Jevons claims for it ; and that he has sought not without success for a method which shall solve the problem of logic generally is a merit of which no criticism can rob him. One may hold the method to be artificial and demur to its theoretic base ; nevertheless it does what it professes to do, does it more simply and satisfactorily than previous systems (like Boole's) 1 Mr. Jevons says Abstraction (p. 79), but this must be a slip. The inverse of Abstraction is not Division but the well-recognised process of Determination. 164 JEVONS'S FORMAL LOGIC. that made the same professions, and apparently it does what the traditional system of logic cannot do. Whatever may be said in favour of the bases of the traditional system, it cannot be denied that its supporters have shown the most persistent indisposition to develop it into an effective uni- versal method of reasoning. It has been passed on from century to century in a crystallised form ; it appears to admit of no development — nay, the boast has been made (though ignorantly) that it was completed once for all by Aristotle ; and practical influence over reasoning, except within a certain narrow range, it seems to have none. For all that appears, the adherent of the old logic gets little or no benefit from his science the moment an argument becomes truly complex and passes beyond a small number of rigid forms. No wonder that earnest logicians like Mr. Jevons, anxious for a truly general theory, should be tempted to break away from a system that has proved so barren, and grasp at analogies that may procure for the theory of reason- ing something of the pliability and fruitfulness belonging to the science of mathematics. The temptation granted, it cannot be too often repeated that Mr. Jevons has signalised himself above other innovators in devising a system that is practically effective without sacrificing (like Boole's) the independence of Logic altogether. At the same time it may well be doubted whether Mr. Jevons would not have done better, if, instead of recon- structing logic from its foundation, he had entered into the spirit of the older system, and, seeing it to be theoretically sound, had indulged his scientific ardour in developing that system so as to make it practically fruitful and useful. All the criticism which it is here possible for me to make upon his crowning Indirect Method is, that I believe it would have cost far less trouble to develop the traditional doctrine to meet the cases of complex reasoning he has in view than to devise a brand-new system to the confusion of Aristotle. It is a case where one must have regard equally to sound- ness of theoretic principle and to ease of practical applica- tion. In the foregoing remarks it has been urged in various ways that the older logic is theoretically sound in its bases and that Mr. Jevons's system is theoretically unsound. JEVONS'S FORMAL LOGIC. 165 How shall one decide between them on the other count of practical utility ? Would it be unfair to take the most com- plex instances of reasoning which Mr. Jevons cites as high triumphs — the highest he gives — of his method, and, if one could show that they are more easily solved by the old logic properly interpreted, then infer that even on the practical side the new system is inferior ? It would not be a decisive test, for Mr. Jevons might bring forward still more complex problems which one knows not beforehand if one could resolve : but at all events it would not be unfair, nor for that matter undecisive against Mr. Jevons as he appears deliberately in his book. Well then ! I affirm that the most complex problems there solved up to those on p. 117 can, as special logical questions, be more easily and shortly dealt with upon the principles and with the recognised methods of the traditional logic ; and till I have cases put before me where this doctrine proves to be practically impotent, I am bound, in consideration of its clear theoretic superiority, to prefer it to the system, however ingenious, of Mr. Jevons. l 1 Take his last and most complex example : " Every A is one only of the two B or C, D is both B and C except when B is E and then it is neither ; therefore no A is D ". Here the mention of E as E has no bearing on the special conclusion A is not I) and may be dropt, while the implication is kept in view ; otherwise, for simplification, let BC stand for "both B and C," and be for "neither B nor C". The pre- misses then are (1) D is either BC or be, (2) A is neither BC nor be, which is a well-recognised form of Dilemma with conclusion A is not D. Or, by expressing (*2) as A is-not either BC or be, the conclusion may be got in Camestres. The reader may compare Mr. Jevons's pro- cedure on p. 117. If it be objected that we have here by the traditional processes got only a special conclusion, it is a sufficient reply that any conclusion by itself must be special. What other conclusion from these premisses is the common logic powerless to obtain ? PHILOSOPHY IN LONDON.1 THE readers of this journal have now had set before them reports on the past and present state of philosophical study at the ancient English universities, and at the younger but still venerable sister-university of Dublin. There are other academic seats in the country that have a history of philo- sophical achievement, and are now active towards issues which it is important to understand. But in the present series of articles there may be some advantage if, before passing to the Scottish universities, and thence extending the survey abroad, attention is drawn to the state of philo- sophical study in London, which is itself the seat of a university, and one moreover that has been called into being within the last half-century expressly to meet the wants of these days. London is the seat of a university, yet one can hardly speak of philosophy at London as at Oxford, Cambridge or Dublin ; and why ? Its mere size, vast beyond comparison though it be, need not keep it from being identified with a university, when other great capitals are rendered illustrious by nothing more than their academic fame. Nor is it necessary that a university should have sprung up in a by- gone age to become the genius of the place : the University of Berlin is but a few years older than the University of London. Eather must the reason be sought in some special disproportion between this university and its metropolitan seat. The University does indeed occupy no very prominent position in London. An examining board which does its work, for the most part, out of all relation to such instruction as the place affords, cannot, whatever its merits may be, play the part of a great informing power whose influence is felt throughout the whole intellectual life of the place. 1 Mind, i. 531. PHILOSOPHY IN LONDON. 167 Merits the University assuredly has, and not least as regards the encouragement of philosophical study, but they avail nothing to bring it into prominence in the world of London. What it accomplishes it does for the remotest corners of the country, nay, for the very ends of the earth, as much as for. London ; and let who will make light of an influence so wide. Yet, if it accomplishes for London nothing more than for the ends of the earth, one sees perhaps how it may bear its name in vain — how the higher education in London itself may be starved for the benefit of unattached learners up and down the country or the alien. The University of London, now fixed in Burlington Gardens, was not the first bearer of the name. The title was originally assumed by a different institution, which, projected in 1825, and established in the imposing building in Gower Street before the end of 1828, was finally con- stituted under its present name of University College in the same year, 1836, that first saw a university founded in the metropolis with the legal privilege of conferring degrees. The original (self-styled) London University was meant to be a university in the Scottish or German sense. Being designed in the first instance for the education of those who by reason of religious restrictions or otherwise were excluded from Oxford and Cambridge, it naturally looked elsewhere for its model. The instruction, duly supplemented by written and oral examinations, was to be given by public professorial lectures, in place of the tutorial system pre- dominant at the older universities. On the other hand, it was far removed from that notion of a university which time and circumstances have actually realised in London. It was to be first and foremost a place of instruction in all the higher departments of knowledge — a true centre of enlightenment befitting the greatness of the capital. The degrees which it hoped to obtain the right to confer were to be given in relation to instruction only. At the same time its scheme of instruction bore one distinctive feature. It was not only, like some other universities (the German and, practically, the Scottish), to assume no charge of the re- ligious education of its students, leaving this to their natural guardians, but it was to have no theological department of 168 PHILOSOPHY IN LONDON. instruction. There was no need, its projectors thought, to undertake a function as regarded the Established Church that was more than provided for at Oxford and Cambridge, and there was no possibility of devising a common system of theological instruction for the variety of sects that would be its first constituents, or for the variety of races that might be attracted to a metropolitan seat of learning. The very circumstances and conditions that necessitated the founding of a new seat of superior instruction for whole classes of the community cut off from all chance of higher culture, seemed to impose the exclusion of theology from the scheme. The claims of Philosophy as a means of liberal education were least likely to be overlooked, for among the founders of the new institution were James Mill and Grote, then a young man much under the influence of the elder thinker. In the first Statement, issued in 1827, respecting the nature and objects of the foundation, there were announced among the professorships to be instituted one of Logic and Philo- sophy of the Human Mind, and one of Moral and Political Philosophy (besides a chair of Political Economy). " As the Physical Sciences aim at ascertaining the most general facts observed by sense in the things which are the objects of thought, so the Mental Sciences seek to determine the most general facts relating to thought or feeling, which are made known to the being who thinks by his own conscious- ness ; " and the Statement goes on to explain how, though " the subdivision of this part of knowledge would be very desirable on account of its importance and intricacy," it would in the first instance be provided for by the chair of Logic, while the chair of Moral (and Political) Philosophy would deal with Ethics as distinguished from the other moral science of Jurisprudence which would also claim the attention of the general student. A Second Statement (1828), explaining in great detail the plan of instruction to be followed in the University, declares in relation to the two professorships that, though the names Logic and Moral Philosophy " are neither correctly indicative of the parts of learning to be expressed by them, nor is such a distribution of the subject thereby effected as strict science would demand, the Council have deemed it better to adopt them PHILOSOPHY IN LONDON. 169 because known and received, than to venture upon others which, if they were less imperfect, would probably, because more strange, be less acceptable". "The Logic Class will have for its province that department of mental phenomena in which all that relates to knowledge or the acquisition and formation of ideas is concerned. The Moral Philosophy Class will have for its province that department of the mental phenomena in which all that relates to action is concerned ; or, more properly speaking, those peculiar states of mind which are the immediate antecedents of our actions, and from which we therefore say that our actions proceed." It was added that as in these classes the youthful mind was introduced for the first time to the great mental pro- cesses of Generalisation and Abstraction, there was "more than usual occasion for constant examination, for the fre- quent prescription of written exercises, and for all the ope- rations of that active study which more speedily imparts a mastery over a new set of ideas than passively listening to a lecture or perusing a book " ; accordingly, a more than usual portion of time would be set apart for those purposes. No less than two hours (one for examination, &c.) every day were to be given to Logic and Philosophy of the Human Mind in the student's third year (along with Chemistry and Natural Philosophy), and nearly as much time to Moral and Political Philosophy in the fourth year (along with Jurisprudence, Political Economy and Natural Philosophy). There are those who will be interested to read of so serious a scheme of philosophical instruction being at that time propounded in London, and I have therefore quoted from the Statements at some length — all the more because the scheme was one that in the event did not find favour with the Fates. In making the appointment to the chair of Philosophy of Mind and Logic (as later it came to be called), differences of opinion revealed themselves within the Council which kept it unfilled till 1830, when it was assigned to the Rev. John Hoppus, a follower of Thomas Brown in philosophy, who continued to hold it till 1866 in the teeth of circumstances that could hardly have been more adverse to the cause of philosophical study. The chair of Moral and Political Philo- sophy has never been filled to this day. 170 PHILOSOPHY IN LONDON. The scheme of philosophical instruction did in truth only share the evil destiny reserved for the whole project to establish in London a true seat of academic influence. It was certainly no mean intelligence that dictated the lines of the project, as any one may yet see who will read the re- markable Statements issued by the Council of the new institu- tion ; and at first everything promised well. The founders, if they underrated the natural obstacles in the way, had some reason for indulging in their hopeful, not to say sanguine, visions of success. The proverbial schoolmaster was then fairly abroad, and there was need of the professor to finish his work. Nor was there wanting to the projected London University the countenance of some in the highest place, and of more who were marked out for power in the coming days of political reform. A sum which reached the figure of £160,000 was quickly subscribed for the rearing of an appropriate edifice and for the due equipment of an instructing staff, which included some of the most dis- tinguished names of the day in literature and science. And yet the project failed to make way. It roused the bitterest political resentment because there were Radicals among its founders, and unmeasured scorn was poured on it because it counted on support from the religious dissenters. The exclusion of theology, however anxiously explained to be inevitable, of course meant a godless institution, and straight- way its foes were moved to establish another seat of superior instruction in London, of which theology should be the corner-stone. Hardly had the so-called University opened its gates in Gower Street, when King's College was set up as a rival in the Strand ; and London, which till then had been devoid of the means of higher education, found itself all of a sudden provided not with one academic institution but with two. Political and religious contention could in a year overdo what centuries had left undone. The young institution was from the first prevented from becoming the great metropolitan centre of instruction which was the main part of its design ; and, in as far as it aimed at securing the legal status of a university with degree-conferring powers, it was doomed to be still more effectually thwarted. The Universities of Oxford and Cambridge would not do the PHILOSOPHY IN LONDON. 171 work it was struggling into being to perform, but they could stoop to crush the semblance of a rival. When the Govern- ment (even after the foundation of King's College) was on the point of granting a university-charter in 1830, it had to be dropped at the last stage, just before passing the Great Seal, because Oxford objected to the liberty of conferring degrees in arts, and Cambridge would not hear of degrees being granted at all. Again moved for about two years later, the grant of a charter was again opposed by the same jealous influences, as arso (with more reason) by the medical corporations and schools in London. To obviate the opposi- tion of these last the claim to give medical degrees was surrendered, and the House of Commons in the first re- formed Parliament (1833) supported the petition as regarded degrees in arts and laws by a great majority. The Govern- ment, however, though not unfriendly, was in a real difficulty by reason of the existence of King's College, which could not be left out of account while it could neither be merged with the " London University " nor incorporated separately with full academic privileges. The only course that seemed open was to create a university over the heads of both institutions, which should have the sole duty of examining while they should have the sole function of giving instruction. In this sense accordingly a resolution was taken, and the University of London was formally constituted in 1836, the parent-institution being at the same time regularly incorporated as University College. The exclusion of theology from the University as finally constituted gave authoritative sanction to the principles that had guided the original movers in their single-minded effort to found in London a home of the higher learning befitting the capital of the country ; and it was with the hope of seeing their dream after all realised that they accepted without a grudge for their costly institution a secondary rank in the academic system. In point of fact, it was still possible that a University in the fullest sense should grow up in London between the new examining board with its State-privileges on the one hand and the two Colleges as they might be developed on the other. But, while nothing more was done either by the State or by private munificence to support and 172 PHILOSOPHY IN LONDON. develop the instruction of the Colleges, it had been provided in the charter of the University that other institutions in or out of London might be affiliated to it, and this provision lay so little dormant that in the next twenty years a host of colleges and secondary schools scattered through the country acquired an equal right with the metropolitan Colleges to send up candidates for examination. There was then an end of the dream. The University might or might not have a useful work to do in the country, and might or might not do it ; but it could never more hope to sway the intellectual life of London. Such as it was during those twenty years, the University of London did by its system of examinations do something to bring forward Philosophy as a subject of study. Every candidate for the B.A. degree was required to pass in Logic and Moral Philosophy, and a man's position here was taken into account in determining the honours-list in classics and mathematics. The higher degree of M.A. might be obtained by a special line of study which consisted of Logic, Moral Philosophy, Philosophy of the Mind, Political Philosophy and Political Economy. Further, the noteworthy regula- tion was enforced from the beginning that Doctors in Medicine should pass an examination in the Elements of Intellectual Philosophy, Logic and Moral Philosophy, unless they had previously taken a degree in arts. The actual requirements, however, within this scheme were trifling enough. Bachelors of Arts were expected only to have read part of Whately's Logic, and, in Moral Philosophy, part of Paley's treatise, with Butler's three Sermons on Human Nature. For the degree of M.D., the examination, at first left open to the discretion of the examiners, came in time to turn upon the first book of the Novum Organum, Cousin's Analysis of Locke's Essay, the first part of Butler's Analogy, and Stewart's Outlines of Moral Philosophy (not so mean a pre- scription of its kind). The M.A. examination remained nominally open, but from the years 1842-3 onwards till 1857 the examiners, Mr. T. Burcham, a police magistrate (who also did duty in classics), and the Rev. Henry Alford, after- wards Dean of Canterbury, were never changed — with the natural result as regards range of topics. The effect upon PHILOSOPHY IN LONDON. 173 instruction as given in the metropolitan Colleges may easily be understood. No candidate preparing for the B.A. degree from University College had the least occasion to attend the professor's lectures on Philosophy of Mind and Logic, and accordingly the professor, having no hold upon the only auditors on whom he might regularly count, lectured during all those years to veiy thinly covered benches. King's College, which had started without any chair of Philosophy and ob- viously set much less store by the subject, was not moved now to acquire an interest in it, and went on without any means of philosophical instruction. No change of any importance was made in the system of philosophical examinations as at first constituted, till under the new charter (9th April, 1858) the decisive alteration in the status of the University was consummated, whereby it was cut loose from all connexion (except in the medical department) with particular places of instruction, metro- politan or other. While the question of the new constitu- tion was still pending, in 1857, the examiners in Logic and Moral Philosophy, Messrs. Bain and Spencer Baynes, then newly appointed in place of the two who had acted together for so many years, addressed a formal representation to the Senate on the state of the examinations and submitted a, very different scheme, which, with some amendments, was finally adopted at the end of 1858 and has since remained in force without further change, except as it was made to apply to the degrees in Science instituted in 1859. By this time Mr. Grote, having brought his History to a close, had become one of the most active members of the Senate (which he joined in 1850) , and his interest in Philosophy, always great yet grow- ing ever stronger with his years, led him to take special charge of the proposed scheme so long as it remained under discussion. As the University was about to admit all comers to its examinations, it was important, while sub- stituting a scheme of reasonable extent in place of the old one, so to frame it as to encourage a resort to systematic instruction ; and to this end it seemed the most effective course to prescribe no particular books but simply to indicate,, as the new examiners proposed, a range of topics represent- ing the main divisions of progressive philosophical inquiry. 174 PHILOSOPHY IN LONDON. The scheme propounded, and at first designed to bear the new title of " Logic and Mental Philosophy," was however vehemently opposed by some of the affiliated Eoman Catholic Colleges on the ground that Mental Philosophy (embracing, as was stated, the Senses, the Intellect and the Will) was a department of knowledge little less vexed by polemics than theology itself, so that the examiners for the time being would be made judges of philosophical orthodoxy ; and also on the ground that, even if no such evil result ensued as the propagation of a system and the creation of a London University school of Philosophy, yet Catholic students would be placed at a disadvantage, being precluded from the study of modern psychological theories till an advanced period of their course, after they were indoctrinated in the body of philosophical truth ancillary to the Theology of the Church (Minutes of the Senate, 1858, p. 87). It was implied, if not expressly asserted, that the previous scheme, prescribing some parts of Whately, &c., was unobjectionable — probably because of its triviality. The Minutes (Dec. 15, 1858) contain a very remarkable statement penned by Mr. Grote in reply to the objections ; and what he urged against the notion of the least design to impose with the weight of University authority a particular view of philosophical orthodoxy, has certainly been borne out by the selection of examiners (no one of whom can serve more than five years running) from that time to the present. Professor Spencer Baynes, one of the present two examiners, has been as much in favour with the Senate as Professor Bain, and the others, in order of appointment, have been the late Professor Ferrier, Mr. Poste, the present writer, the Hector of Lincoln, Mr. Venn and now Professor Jevons. The principle of the scheme of examinations in Logic and Moral Philosophy (the old title being in the end retained), as it came into full working order from the year 1860, is a very intelligible one. A minimum requirement for the degree of Bachelor of Arts, or of Science, is variously extended and intensified for the grade of Bachelor with Honour, and for the higher degrees of M.A. and D.Sc., while it is (in practice) somewhat attenuated for the professional degree of Doctor of Medicine or Master of Surgery. The University of PHILOSOPHY IN LONDON. 175 London exacts a certain amount of philosophical knowledge from every Bachelor of Arts as part of a general liberal educa- tion, and from every Bachelor of Science as part of his general scientific equipment. " Names, Notions and Propositions, Syllogism, Induction and subsidiary operations " mark with sufficient plainness the scope of the examination in Logic ; and the heads " Senses, Intellect and Will, including the Theory of Moral Obligation" show that Moral Philosophy is understood in the wider sense of Mental Philosophy, while this last is interpreted chiefly as Psychology. Bachelors, whether of Arts or Science, may thereupon subject them- selves to a more protracted (two days instead of one) and severer trial in the same subjects, supplemented by the topic of "Emotions," and with the " Theory of Ethics " brought into greater prominence : a scholarship of i'50 for three years may here be gained. The Bachelor of Arts who now proceeds (after not less than eight months) to the special degree of Master will, if he chooses Branch III., be subjected (for three days) to examination in the old topics (only Ethical Systems instead of Theory) supplemented by a special prescription, varied every year, in Political Philosophy and History of Philosophy,1 besides Political Economy (one day) : here may be won a gold medal worth £20. The still more special degree of Doctor of Science, open only to Bachelors of Science of not less than two years' standing, may be taken in " Mental Science," with the main topics as for M.A. set out as principal subject, and the following as subsidiary subjects — " Physiology of the Nervous System and Organs of the Senses in man and other animals, History of Philo- sophy, Political Philosophy, and Political Economy " (in all four days) : "a thorough practical knowledge of the principal subject and a general acquaintance with the subsidiary sub- jects " is here required. Finally the degree of M.D. or M.S. cannot be obtained without a philosophical examination (three hours), of which the nominal scope coincides with that for the B.A. or B.Sc. degrees, though there is a tacit understanding that 1 For 1876 the subjects were : Political Philosophy — Ideal Polities or States, their nature and use, with special reference to Plato's Republic, More's Utopia, and Bacon's Neio Atlantis; History of Philosophy — The development of Locke's principles, Berkeley's Principles of Human Knowledge and Hume's Treatise of Human Nature. 176 PHILOSOPHY IN LONDON. those aspects of the subjects should chiefly be considered that are least remote from the field of medical practice. The scheme, it will hardly be denied, is not only clearly conceived but betokens a real concern for the promotion of philosophical study and work. That philosophy should form part of every liberal education (B.A.), and that it may then well engage the special attention of more advanced students (M.A.) before taking up with a particular profession ; that Psychology and Logic have their place in a general scientific discipline (B.Sc.), and that mental research in one or other of its departments may claim the life-long devotion of trained scientific powers (D.Sc.) ; lastly, that every medical man who aspires to the higher dignities of his profession (M.D., M.S.) should have bestowed some express thought on the laws of evidence and on the hidden mental life inwoven with the bodily frame — such is the meaning of the scheme ; and where is there another university that makes so system- atic a stand for the cause of philosophy in education ? It should not be forgotten that even in the early years of the University the importance of the subject had been, in name at least, recognised, in deference, it may be supposed, to the principles of the original movers for university-education in London ; and thus it was easier for an earnest friend of philosophical study like Mr. Grote, himself one of them, to get the reformed scheme in its completeness set on foot when the new constitution imposed upon the Senate the duty of making the examinations at once broad and effective. On looking, however, beyond the scheme itself to its actual working, there seems less ground for satisfaction, and the reason will perhaps be found to lie in that very peculiarity of constitution with reference to which the scheme was so carefully devised. The Senate would no longer require of candidates for degrees that they should have been instructed in particular colleges ; but it hardly expected that a great proportion of them would cease to frequent any place of instruction. It started with an earnest determination to maintain a high standard of requirement : it did not foresee that away from a base of instruction the standard could be neither constant nor high. It was certainly from no desire to discourage systematic instruction that the more enlightened members of the Senate PHILOSOPHY IN LONDON. 177 stood by the plan of opening the University examinations to all comers in the teeth of strong remonstrance from all the more important affiliated colleges. With affiliation carried out as it had been in the first twenty years, the truth was that no shadow of reason remained for excluding almost any decent secondary school from the list of the institutions whence the University received certificates for degrees in arts and laws ; and the only sensible step forward, when there was no question of taking a great many steps back- ward to the original position of founding in reality as in name a University of London, was of course to admit candidates without reference to their place of instruction. This had become clear, not only to the majority of the Senate, who from one motive or another had gone on relaxing the conditions of affiliation, but also to those members (like Mr. Grote) who had struggled in vain for the maintenance of stricter principles ; and the step once fairly contemplated, there was no stopping short of the final position that the University should confine itself to its own work of examining, whether or not candidates had been regularly instructed at all. It all followed as naturally as possible from the University being set up, not as a means of organising the higher instruction in the capital, but to perform directly a certain useful kind of work for the country at large. At the same time the notion of fair and open examination for all with perfect free-trade in teaching had an air of liberalism about it that imposed on many minds, as it still is the idol of Mr. Lowe ; and it was only to be expected that some ardent advocate should urge what lustre would be shed on the University that welcomed to its examinations "the heroic stonemason," beholden to no college whatever for instruction. Nevertheless, as I have said, the intention of the best heads was rather to encourage than depress instruction, and as regards the initial (B.A. and B.Sc.) examination in Philosophy it was even expressly intimated that the amount of acquirement expected was such as might fairly be attained by a course of instruction in a class during the year preceding examination. It is interest- ing then to see what kind of philosophical study the scheme of the University has in practice evoked during the last fifteen years. 12 178 PHILOSOPHY IN LONDON. The broad result is that a full half of the yearly tale of Bachelors of Arts (to take the most representative class -of graduates) acquire their knowledge of philosophy by private reading without instruction, while the proportion of such private students to the whole number of candidates for examination is considerably greater. Of the others who pass as Bachelors, some ten or twelve may have had more or less of formal instruction in Catholic or Dissenting theological colleges, and the rest are students of the only two general academic institutions that remain in any sort of regular connexion with the University, namely, University College, which sends up yearly about a dozen men, and Owens College, Manchester, whose usual quota is less than half as many. (King's College, which still does not include Philo- sophy in its scheme of instruction, has practically ceased to maintain any relations with the University of which it was to be a chief feeder.) Now the number of students who go up from University College shows no tendency to increase, and the authorities of Owens College have just made it part of their plea for being turned into an independent university that fewer and fewer of their instructed students care to look to the London examinations. Some serious questions thereupon arise. What is the effect on the philosophical examinations of the unexpected predominance of private- study candidates ? And what is the real value of the carefully elaborated scheme for candidates of that class ? I am afraid it must be answered that, in such circumstances, an examination tends to become whatever test a fair pro- portion of candidates for the time being are found able to pass. Nobody is to blame, and yet it is so. The authorities may be sincerely anxious to maintain a good standard, the examiners may set the most carefully considered papers ; all the same, when the list of the rejected comes to be determined, it is not in human nature not to take account of the actual performance of the bulk of the candidates and accommodate the standard to the exigencies of the occasion. Then the candidates, in course of time, discover that certain books most nearly correspond with the scope of the examination, and the examiners, however careful they may be to put open questions, cannot refuse a stereotyped PHILOSOPHY IN LONDON. 179 form of answer or bear hard on those candidates whose obviously limited reading has left them without the means of answering any but a determinate class of questions. Thus practically the examination comes to turn upon books after all ; and the formal divorce of the University from any system of instruction leaves it to be supposed that the reading of one or two philosophical books constitutes an effective mental discipline. But nothing could be more fallacious. I doubt if any one who has read the written answers of the multifarious crowd of candidates for the B.A. degree, the majority of whom have come into contact with no living instructor, can hold it an unmixed good that an examination in Philosophy is imposed upon all under the present constitution of the University. The subject, so nearly concerning every reflective human mind, and most fitly therefore regarded as crowning a liberal education, is yet the one of all others that may least be left to undirected private reading in the case of the mass of students. Certainly there are a few minds here and there, now and again, who with or without formal instruction follow a native bent and can be trusted to work their way to clearness and coherence of thought on the questions of human origin and destiny, but with the multitude of learners it is quite otherwise. A little book knowledge of philosophical questions, when not a dangerous, is truly a most unprofitable thing. That general students may profit by a course of philosophical instruction there is the experience of the Scottish Universities to show ; and the number of distinguished thinkers who have risen in the ranks of Scottish professors represents a real national gain yielded by an organised system of public instruction in Philosophy. It is to be charged against the London Uni- versity that all its elaborate machinery does nothing to help on the work of instruction, but rather has the contrary effect as regards the higher elements of human culture. At least as respects Philosophy, while it is certain that Grote and others looked forward to a great development of instruction, the ad- vance made in the last fifteen years has been quite insignificant. University College has its professor of Philosophy of Mind and Logic who lectures year after year to a small voluntary class of young students attending the College, with a few 180 PHILOSOPHY IN LONDON. additional hearers from without, but has no constituency to draw upon for higher work in the subjects, because candidates for the special degree of M.A. at the University are a handful altogether in any year, and, besides, are scattered through the country, or, if in London, are generally engaged already in some active pursuit interfering with continuous study. Owens College in Manchester has a professor who as yet at least is in no more favourable position as regards auditors, while he is weighted with the additional subject of political economy. Besides these two there is no other public professor of Philosophy in all England outside of Oxford and Cambridge. Such instruction as is given in some Dissenting theological colleges or in Catholic colleges is of course discounted, though it should not be forgotten that one theological seminary in London has long been signalised by the teaching of Mr. Martineau. The statement whether as regards the country ,or as regards London will sound incredible to foreign ears, and may astonish even English readers when presented in its nakedness. Meanwhile the old Universities, as the readers of this journal have been told on the best authority, do not come near to discharging the national work that is otherwise left undone ; however great be the credit due to the band of earnest instructors who are labouring to establish a due balance of education at Cambridge by the revival of Philosophy, or whatever be the evidence of serious thinking at Oxford at a level high above the arena of the examination- schools. One can only hope for a day to come when in London some organised system of highest instruction will supersede the wasteful efforts .of rival institutions now ill- equipped or incomplete, and trust that in that day the import- ance of Philosophy as a mediating influence between letters and science will be fully recognised. How the reform may be brought to pass, there is little as yet to show. Perhaps the University of London, having done a good work in stirring up the country to a sense of the need of broad secondary education, will after all be transformed, for the good of the country's capital, into the likeness of that original seat of high learning which was projected to bear the name ; taking up into one coherent academic system the two Colleges that sprang out of the first movement and the PHILOSOPHY IN LONDON. 181 special scientific schools that, by a lavish appropriation of public money, have in later years been founded without the least regard to the private sacrifices made half a century ago. Perhaps University College itself, as the original depositary of the academic trust for London, will, after its long struggle with faint success to make the higher education self-supporting, receive from public or private sources the endowment that all human experience has proved to be indispensable for its maintenance, and will expand into a great school of all science and learning that need not look outside to the cramping standard of even the best examining body that is nothing else. In one way or another the reproach that adheres to superior instruction in London and to philosophical instruction with the rest cannot too soon be taken away.1 1 Within the last few months a Society has actually been formed with the professed object of organising University Education in London, and as, in the view of the foregoing article, the question of philosophical instruction is bound up with the larger problem, a word or two upon the latest attempt to solve it may not be out of place. The Society has arisen out of a movement by one or two meritorious institutions that give instruction in the evening to persons engaged in business by day. These were desirous to obtain the services of young Cambridge lecturers like those who in late years have been breaking ground in northern towns ; but oddly enough, the humble design was given out as the beginning of a scheme for University Education in the metropolis, as if such a thing had never before been thought of, and London were another Nottingham upon which a reflexion of academic light might be induced to fall. Soon, however, the movers and their influential friends, some of whom were less ignorant than forgetful of what had been done in former days, awoke to a sense of the difference between London and a provincial town, and the scheme then took a new shape. The notion was now to invoke the two older Universities with the University of London to take the metropolitan field in charge with the view of supplementing the instruction already given within it, and a very elaborate working- plan was devised. But as Oxford and Cambridge have since declined the proffered charge, the Society is left to make what way it can within London itself. One desires to speak with all respect of any serious effort directed towards the end proposed, and there has undoubtedly been no small energy displayed in the establishment of this Society. The observation cannot however be forborne that its founders have from the first kept before them no distinct conception of what is meant by University Education. If their main object, as there is still some reason to suppose, is to provide additional evening instruction in different parts of London, the name of University Education is surely misapplied. If, on the other hand, it be true academic work which they are eager to foster, the sjjnplest way, one would think, is to develop the two Colleges that have struggled to maintain the higher learning for nearly fifty years past. But it would seem as if in London there were never to be an end of new beginnings. 182 PHILOSOPHY IN LONDON. Supplementary Note. — For an important change (of principle) in the B.Sc. regulations, just announced, see News at the end of this number. Since the article on Philosophy in London in the present number was written, an important change has been announced in the plan of examina- tions for the degree of Bachelor of Science in the University, whereby Logic and Psychology will cease to be compulsory subjects ; and thus vanishes one of the most characteristic features of the general scheme of the University as set forth in the article. The B.Sc. examination will as before consist of two stages, but will not henceforth have reference to a merely general discipline in the sciences. At the second stage, instead of being required as heretofore to pass in five different subjects making with the four subjects of the first stage a tolerably complete round of the chief sciences, a candidate in future need not bring up more than three out of nine subjects, of which Logic and Psychology form one. That is to say, he will begin to specialise before reaching the grade of Bachelor. Care, however, is taken to make the earlier examination more comprehen- sive than hitherto — in fact, fairly co-extensive with the field of general science as commonly understood. The practical and other reasons for the change are very strong, nor is it greatly to be regretted, in the pre- sent state of instruction or feeling about instruction as described in the article, that the philosophical examination will no longer be imposed on all the candidates. At the same time it is right to point out that the general scheme of the University is dislocated by giving the B.Sc. degree (even partially) a special character ; while if Logic and Psychology are allowed (as they are) to rank as Science, they cannot properly be ranged (as they are) with departments so special — not to say concrete — as botany, zoology, or physical geography and geology. About Psychology there may be a question, if it is not clearly conceived as the great fundamental sub- jective science — the root of one half of human knowledge, or rather, the key to one whole side of all human knowledge ; but surely Logic at least pertains to the most general scientific discipline. In no longer requiring a knowledge of Logic from its Bachelors of Science, the University is throwing away one of its chief distinctions, and will not so easily replace or recover it. No change has been made in the regulations for admission to the degree of D.Sc., except that candidates who have prolonged the interval between the first and second stages of the B.Sc. examination from one year to two years or more, over their special studies, may go up for the Doctorate after a single year instead of two years as before. This change seems a reasonable one in the new circumstances ; but the reform really called for in the D.Sc. regulations is that some evidence of original work should be required from the candidates, by way of written dissertation or otherwise. In the department of Mental Science at least, the written answers to papers of miscellaneous questions which are at present the only test imposed, keep the degree practically at the level of the ordinary M.A. (Branch III.), except in so far as the greater range of subjects implies a longer and wider study. But this very width of range - extending from PHILOSOPHY IN LONDON. 183 Physiology of the Nervous System through Mental Philosophy (in all its branches) to Political Philosophy — is itself a grievance. When a man has begun to specialise to any purpose, he will find in any one of the subjects indicated occupation enough — supposing that " a thorough practical knowledge " is by all available means exacted. It is doubtless because of the extreme width of the range of the examination that in all the last sixteen years since the degree was instituted, no more than two candidates have presented themselves for the Doctorate in Mental Science. One of them, Mr. P. K. Bay, a native of Bengal, has this year succeeded in passing, but such a result is hardly a sufficient justification of the present examination-scheme. THE LOGIC OF "IF".1 I HAVE lately come across a passage in Clarissa Harlowe where Richardson indicates with great clearness a dis- tinction which has long seemed to me to be overlooked by logicians in their treatment of Hypothetical Syllogism. It is in the admirable scene where Morden and Lovelace are first brought together, and runs thus; : Morden : " But if you have the value for my cousin that you say you have, you must needs think " Lovelace : "You must allow rue, sir, to interrupt you. If I have the value I say I have. I hope, sir, when I say I have that value, there is no cause for that if, as you pronounced it with an emphasis." Morden: " Had you heard me out, Mr. Lovelace, you would have found that my if was rather an if of inference than of doubt." The question has been much debated among logicians whether the so-called Hypothetical Syllogism of this type If A is B, C is D But A is B /. CisD is a mediate inference like the common Categorical Syllogism, or whether the conclusion is not immediately drawn from the one premiss ' If A is B, C is D '. Prof. Bain, for example (Logic, i. 116), would deny that the reasoning is mediate, and the reader may consult his work for a short summary of the different arguments urged by Mansel and other dis- tinguished logicians on the same side of the question. Some of the arguments, indeed, are too plainly defective, as when Mansel declares that in the Hypothetical Syllogism " the minor (A is B) and the conclusion (C is D) indifferently change places and each of them is merely one of the two members constituting the major " — which is not the case in Categorical Syllogism. Here he commits a very great blunder, since it is notorious that ' A is B ' cannot be got as 1 Mind, ii. 264. THE LOGIC OF "IF". 185 a conclusion with ' C is D ' as second premiss. However, the whole weight of authority in favour of the inference being immediate is undoubtedly great, and if one takes the other view, some explanation must be found for the strong array of opinion that may be cited against it. It seems obvious enough that when the proposition ' If A is B, C is D ' is uttered as a pure hypothesis — the if, as Richardson expresses it, being one of doubt — it is not pos- sible to pass directly to the assertion that ' C is D '. This can be reached only through the other assertion ' A is B ' ; and what is the reasoning then but mediate ? If the con- clusion, which is quite a different proposition from the original datum, is here not mediately reached, there is no such thing as mediate reasoning in categoricals. Whatever meaning there is in saying that given ' M is P,' we arrive at the different proposition 'SisP' only mediately— through 4 S is M,' there is as much meaning in saying the like of ' C is D ' obtained as a positive assertion from the supposi- tion ' If A is B, C is D ' only through the positive assertion ' A is B '. For that matter, the categorical major ' M is P ' can itself be expressed as a hypothetical ' If M, then P ' ; then follows in the minor an assertion of M (namely S) ; whence as the conclusion an assertion of P. The only immediate inferences that can be drawn from the purely hypothetical proposition ' If A is B, C is D ' must them- selves be hypothetical. These namely follow : ' If C is not D, A is not B,' ' In some case (at least once) where C is D, A is B ' — the logical contrapositive and converse respectively of the original. But these are utterly unlike the conclusion 4 C is D ' got from the same hypothesis through the assertion 4 A is B '. With what reason, then, can it in any case be maintained that ' C is D ' is immediately got from 'If A is B, C is D ' ? With very good reason, when if, instead of meaning suppose that, is used for since, seeing that, or became. It is plain that the original proposition may be thus understood : ' Since A is B, C is D '. Or take a material case. ' If it rains, the street is wet,' interpreted strictly as a bare supposition, can never of itself lead to the categorical assertion 'The street is wet ' (as a matter of fact) : it only involves immediately 186 THE LOGIC OF " IF ". such other suppositions as these — ' If the street is not wet, it does not rain,' ' If the street is wet, it may be from rain '. But the same expression is also used on a very different occasion : ' It rains (do you say ?) , why then of course the street is wet,' ' To be sure the street is wet, for does it not rain ? ' ' No doubt, as it rains, the street is wet '. Here we know immediately that ' the street is wet ' (or C is D), for this is the assertion in the proposition ; and the 7/-clause is not proposed as a possible ground for a conclusion, but is stated shortly as the actual reason of a fact. When ex- panded, it corresponds not to the first premiss of the Hypothetical Syllogism, but to the two premisses together. That is to say, if the clause is regarded as containing a supposition at all, it contains, besides the formal supposition ' If A is B, C is D,' the positive assurance ' A is B '. Of course from the two premisses thus taken together, the con- clusion ' C is D ' follows at once or immediately ; but the same is true of the conclusion of a Categorical Syllogism as following from its two premisses. Now, when if thus covers an assertion of fact within a supposition, it may be called, as by Richardson, an if of inference, as containing the whole reasoned ground of the last clause in the sentence. But such a sentence is no longer the ' hypothetical proposition ' of logic— that kind of thought-utterance which, though it has a different form, is as simple as the simplest categorical proposition, seeing (as before suggested) there is no cate- gorical proposition which may not be expressed as a hypothetical, and vice versa. The true and simple sense of If in the antecedent part of a purely hypothetical proposition may be otherwise brought out by considering its analogy with the subject in a cate- gorical. Take a 'proposition in Euclid. It is exactly the same whether we say, ' The angles at the base of an isosceles triangle are equal,' or 'If a triangle is isosceles, the angles at its base are equal ' ; and Euclid, like everybody else, falls as readily into the one expression as the other. Now to suppose that the consequent in this pure hypo- thetical is immediately given with the antecedent or follows from it directly, can amount only to saying that the predicate (in the categorical expression) is directly implied THE LOGIC OF " IF". 187 in the subject ; or, in other words, that the proposition is analytic. But it is, as we know, in this case synthetic, and to bring about the synthesis an express proof is necessary. Just so we must not think of getting the consequent of a pure hypothetical from the antecedent except in the case where there is direct implication, as ' If triangle, then trilateral '. It is worth while adding in this connexion that the other form of proposition ranged by logicians with the Hypo- thetical, namely the Disjunctive, may be shown to be as simple as the pure Hypothetical, being in fact a special case of it. The common view is that it involves at least two hypothetical propositions, or, as some say, even four. Thus ' Either A is B or C is D ' is resolved by some into the four hypothetical — If A is B, C is not D (1) If A is not B, C is D (2) If C is D, A is not B (3) If C is not D, A is B (4) — but the first and third of these are rejected by others, and with reason, because they are in fact implied only when the alternatives are logical opposites. The remaining proposi- tions (2) and (4) are, however, the logical contrapositives of one another ; and this amounts to saying that either of them ~by itself is a full and adequate expression of the original disjunctive. ENGLISH THOUGHT IN THE EIGHTEENTH CENTURY. ' BESIDES the remarkable work whose name is placed at the head of this article,2 two other important contributions have recently been made to the history of philosophical thinking in England. Prof. Kuno Fischer has taken his old mono- ' graph on Francis Bacon (known to English readers since 1857 in Mr. Oxenford's translation), and so recast and enlarged it as to give not only a more adequate representa- tion of Bacon as a man and thinker, but an account of the development of the ' Philosophy of Experience ' as far as Hume, no longer quite too meagre to stand as a side-piece to that history of Modern Philosophy which he has traced on a great scale from Descartes through Spinoza and Leib- niz to Kant and his successors.3 The book in its new form appeared in 1875, and in the same year, by a curious coin- cidence, the late M. de Remusat, who had before followed close on Fischer with an independent monograph on Bacon, came forward with a History of Philosophy in England from Bacon to Locke* There is evidence of genuine • research in this work, especially among the less-known writers of the seventeenth century, which should have drawn attention to it in England before this time. On the present occasion it is simply mentioned, because of the period which it seeks to compass. Where M. de Remusat leaves off, there Mr. Leslie Stephen in his brilliant volumes may be said to take up the 1 Mind, ii. 352. 2 History of English Thought in the Eighteenth Century, by LESLIE STEPHEN. 2 vols.

ENGLISH THOUGHT IN THE EIGHTEENTH CENTURY. 189 tale ; and, though there could not well be a greater difference in the spirit and scope of the two works, there is much in the later history that may be better understood for the careful record of the earlier time which we owe to a foreign hand. Much as he has to say about philosophers and their work, great and small, Mr. Stephen has not written or professed to write a History of Philosophy in the stricter sense. His aim and even his method of constructing the book are disclosed with the utmost candour. It was his first object to trace systematically and in full detail the course of Religious Thought from 1(588 to 1750, the period defined and rapidly sketched in Mr. Pattison's well-known essay. Lechler, more than thirty years ago, gave an adequate account of the Deists proper, but did riot concern himself, save incidentally, with their orthodox opponents, though these (as Mr. Pattison sought particularly to impress) betrayed the same general tendencies of thought. It accordingly seemed necessary to Mr. Stephen to trace back the common theological tendencies of the age to the philosophical ideas then prevalent ; and upon this there was an interest in showing how the principles accepted in philosophy and theology were applied to practice in the sphere of moral and political thought, or, again, reflected in the imaginative literature of the time. As thus explained, the scope of the book is of course very different from that of a technical History of Philosophy, and it is in fact so com- prehensive that almost everything appears to be included in the author's survey of thought or intellectual activity in the century, except the work of special science. Is he justified in giving to the word Thought at once such an extension and such a restriction, as to include in the same treatise with thinkers like Locke and Hume and Butler, poets and novelists and preachers like Burns and Fielding and Wesley, to the exclusion of scientific inquirers like Newton or Black or Hunter ? Mr. Stephen, though himself doubt- ing whether his title is not too ambitious, evidently is guided by some definite principle in determining the scope and limits of his work ; and perhaps it may be gathered, in default of more express statement, from the beginning of his last chapter, where he passes, after dealing successively with philosophers, theologians, moralists and publicists, to the 190 ENGLISH THOUGHT IN THE EIGHTEENTH CENTURY. delineation of what he calls the ' Characteristics ' of the age. The literature of a people, we are told, may be disposed under three heads : (1) historical, which records facts and sum- marises or amplifies existing knowledge ; (2) speculative, which discusses the truth of the theories binding knowledge together ; and (3) imaginative, which utters the emotions generated by the conditions in which men are or believe themselves to be placed. Here, Science is either excluded from Literature altogether as a technical pursuit, or it is included in the wider sense of History, which regards nature in all its varied aspects as well as man. In either case, since History itself is not brought within Mr. Stephen's scheme, Science as the sum of existing positive knowledge about the world is naturally excluded. But besides the properly philosophic thought which seeks rationally to co-ordinate the variety of human knowledge with a view more or less direct to practical conduct, it is natural to consider the imaginative synthesis, since by this (as he urges) is determined the action of the majority of mankind, and further (as he might have added) because the philosophical synthesis, not being in the same way verifiable as the generalisations of positive science, must alwrays contain an element of subjective sentiment allying it to imaginative literature. If some such view was present to Mr. Stephen's mind, there is not wanting a good reason for the limitation of subjects in his book ; while, on the other hand, his readers may be glad that he has so far widened his scheme as to give them, in his well and often brilliantly written pages, a varied picture of national thought and feeling alive with human interest, instead of the abstract and one-featured record, apt to be mis- leading, which History of Philosophy commonly is . Nor in this case at least is good literary effect procured at the expense of careful research. The one objection, perhaps, in point of form, that can be brought against the book as a History of Thought, is the unequal prominence given to the phases of religious as compared with philosophical opinion, — if it is not too ungracious to say so, when Mr. Stephen has implied in his ingenuous preface that, but for his interest in the reli- gious movements, we might not have had from him a view •of the century at all. ENGLISH THOUGHT IN THE EIGHTEENTH CENTUBY. 191 In Mr. Stephen's view one figure stands forward at the beginning, and re-appears towering above all others in every scene of the history. Whether it be the philosophy, or the theology, or the morals, or the politics of the century that is under review, the decisive word, representing the last out- come of what was in men's minds, is always uttered by Hume. Half-way through the century dogmatic speculation about the supernatural ceased of a sudden : Hume had spoken, and ever afterwards those who were concerned to save the conclusions of metaphysical philosophy had no choice but to try for them by another road. About the same time the hot theological warfare that had filled the world with clamour for two generations died away : Hume had sprung a mine that sent into the air both deists who were not Christians, and Christian apologists who were but deists. It took fifty years from the time of Locke before the utilitarian ethics, so congenial to the national mind, got a definite philosophical expression — from Hume. Hume left nothing unsaid which the acutest intellect could say about political philosophy so long as men were supposed independent atoms, and there was no thought of organic evolution or serious consideration of historical development. And if the histori- cal spirit began to awake in the second half of the century in preparation for the work of the age to come, even in this forward movement Hume too had part. When we remem- ber, besides, who it was that almost disowned the rugged work of his strong youth, and desired to be judged by the fastidiously polished but less searching essays of his prime, we see with what reason Mr. Stephen may take Hume as quite the representative thinker of a century quick with intellectual activity, only not the deepest. Should we try, further, to gain a comprehensive view of the whole course of thought in the century, as it presents itself to Mr. Stephen, the spectacle resolves itself into a number of scenes which, described in very general terms, are these : (1) A movement of determined philosophical criticism lasting fifty years or more from Locke to Hume, destructive of the whole edifice of speculative metaphysic reared by Descartes and his followers in the seventeenth century, but neither itself constructive otherwise nor exciting (in England), while the 192 ENGLISH THOUGHT IN THE EIGHTEENTH CENTURY. century lasted, any philosophical construction of real and permanent importance. (2) A rationalistic movement in religion, prepared in the seventeenth century, and following naturally from the principles of Protestantism, at first pro- moted by the influence of the current philosophical ideas, yet in the end suppressed by the advance of philosophical opinion, or changed into a historical investigation of the external evidences for a supernatural revelation. (3) A movement to find a rational ground for moral action, by way of supplement to the weakened force of the theological sanction, or as a substitute for it when altogether rejected. (4) A corre- sponding movement, less earnestly maintained, to explain on rational principles the social and political relations subsisting between men, upon the decay of the notion of supernatural ordinance. (5) Within this last movement, a special deter- mination towards economic inquiry. (6) Finally, a varied literary movement, at first reflecting very faithfully the dominant philosophical and religious conceptions, but after- wards, as these became effete without begetting others, opening out into new lines of sentiment which anticipated the rational thought and inquiry of the coming time. It is not possible, in short compass, to do anything like justice to the working out of so comprehensive a scheme as this of Mr. Stephen's, but as the philosophical and ethical movements, which are of special interest to the readers of this journal, happen to be rather compendiously treated, we may look a little more closely at his view of these. The dogmatic philosophy which the ' English Criticism ' broke down was the metaphysical system inaugurated by Descartes, and, according to Mr. Stephen (though the point is never very clearly established and is more than doubtful), the same system, with its abstract assumptions and deductive method, dominated the minds of the chief English rationalists in religion, whether orthodox or deistical. He therefore begins with a short account of the Cartesian philosophy. He makes no reference to Bacon, and but incidental reference to Hobbes, the great English thinkers of the seventeenth century, and this may appear strange ; yet there is reason for the omis- sion. Bacon and Hobbes were, each in his generation and in his own way, true representatives of the English spirit in ENGLISH THOUGHT IN THE EIGHTEENTH CENTURY. 193 philosophy, but it was not till Locke abandoned any such attempt as either of theirs to construct an objective system of universal knowledge, and threw himself upon a critical investigation of the mind's powers, that England joined properly in the modern philosophical movement of Europe. It is true that Descartes himself, the great leader of the movement, had sought, from his philosophical starting-point, to work out also an explanation of the concrete phenomena of nature. Before the end of the seventeenth century, however, the attempt was practically discredited by the advance of positive physical science from the time of Galileo ; and Locke showed a true appreciation of the Zeitgeist, when, in an age that produced " such masters as the great Huy genius and the incomparable Mr. Newton, with some other of that strain," he thought it " ambition enough to be employed as an under- labourer in clearing the ground a little, and removing some of the rubbish that lies in the way to knowledge". In words of too great modesty, we have here from Locke himself a statement of the true work of philosophy in modern times, and we see how in him English philosophical thought comes into relation with the general European movement which, however diverted by this or that speculative genius, has always been directed to the fundamental inquiry as to the ground and limits of knowledge. In particular, the Cartesian philosophy was an attempt to found certainty of knowledge upon the immediate deliverances of adult consciousness, without consideration of the sources and development of knowledge, and in respect of method sought to proceed by way of rational deduction in constructing a fabric of meta- physical doctrine. This was exactly what Locke set himself from the very foundation to oppose. That the question of the validity and limits of knowledge must depend upon an inquiry into its origin and development was his deepest philosophical conviction ; and though, as Mr. Stephen well points out, he and his successors till Hume were really at one with the Cartesians in restricting the inquiry to the consciousness of the individual as known by introspection, and had not a different conception of the meaning of real existence, yet the difference of method could not but lead to very different conclusions. How far Locke himself applied the critical 13 194 ENGLISH THOUGHT IN THE EIGHTEENTH CENTURY. solvent to the system of dogmatic metaphysics, and how, with diverse aims, it was further applied by Berkeley and Hume, is clearly and vigorously set forth in general lines by Mr. Stephen. The result was what we know — that rational speculation by itself, apart from experience, was stripped of all authority. Mr. Stephen, having always more than an antiquarian interest in his subject — being, in fact, for a historian, too much rather than too little apt to sit in judgment, as well as set forth and explain — is especially careful to consider the attitude of Hume, so as to find a way out of the deadlock to which the great doubter seemed to bring all human inquiry, while shattering the system of speculative metaphysic. He finds that Hume's point of view was essentially artificial ; that he did not think of the mind of the individual in its true relation to the social organism — as moulded by influences quite different from the disjointed and haphazard sense- impressions out of which he supposed the whole fabric of intellectual consciousness had ever anew to be reared by and for each person ; that he had 110 historical sense, much less a glimmer of that scientific notion of the evolution of all organic life which since then has so profoundly affected the work of philosophical interpretation. The criticism, though not very elaborate, is, as far as it goes, admirably conducted, and is an attempt of a kind that has been too seldom made by sym- pathisers with Hume's philosophical spirit to maintain it intelligently in the altered state of human knowledge since his time. As such, Mr. Stephen's judgment deserves the attention of those champions of a different philosophy who seem to think that a textual sifting of the writings of Locke and Hume, revealing manifold inconsistencies and defects of thought, is the most effective way of dealing a death-blow to the cause of Experientialism at the present day. But — in exhibiting Hume as the hero of a philosophic movement, which effectually accomplished a work of destruction, yet did it from principles which could lead to no constructive result, so that only after a long lapse of years and by means of varied research in history and special science was there gradually formed, in these latter days, something like an adequate experiential philosophy — Mr. Stephen has not given sufficient ENGLISH THOUGHT IN THE EIGHTEENTH CENTURY. 195 prominence to one very marked phase of English intellectual inquiry in the eighteenth century, and has thus been led to do some injustice, if not to Hume's predecessors, at least to his contemporaries and successors within the century. Psychol- ogy, if it is viewed as science, has yet an exceptional standing in relation to philosophy, and cannot be neglected in a history of philosophic thought in England, where it has been so steadily cultivated without being too carefully discriminated from philosophy proper. Now Mr. Stephen, in his exposition, nowhere gives much attention to the progress of psychology, though this was very remarkable within the century ; and hence he fails to assign due importance to one in particular of Hume's contemporaries — David Hartley. His somewhat disparaging estimate of Reid, in the last generation of the century, might also have been relieved by an allowance of serious purpose as a psychological inquirer to one who him- self achieved something, and moved others to achieve more. It should be well understood that Locke's work, the begin- ning of all that followed in England, had two sides, which, however related to one another, maybe clearly distinguished, and were in fact the occasion of two different lines of development in English thought. Essentially a philosopher in his concern for the general problem of knowledge, he sought for the solution of it in a psychological spirit, and he was the first who expressly took up this position. He differed from his predecessors, not only in his philosophical conclusion, but from all of them — even his own countryman Hobbes — in putting forward the psychological question of the growth of knowledge as the first to be answered. And however undeveloped his own psychology was, it soon appeared from what followed how effectively he had given an impulse to new inquiry. Berkeley did not only philosophise after the manner of Locke, showing, with the special theological purpose that moved him, how all knowledge was based on experience, and that no experience could be assigned portending an absolute existence of matter : he began in his New Theory of Vision the work of special psychological investigation after the manner of positive science. Even Hume, though his lasting import- ance consists in his properly philosophical activity, set out at the beginning with the distinctly psychological aim of found- 196 ENGLISH THOUGHT IN THE EIGHTEENTH CENTURY. ing a " science of man " on " experience and observation " like " the other sciences," or, as he also expressed it, of making an "application of experimental philosophy to moral subjects," as it had already been made to physical nature. Now what Hume thus professed to do, but diverging into the critico-philosophical vein left for the most part undone, this Hartley expressly essayed and carried through, however he may have also sought to combine therewith an extraneous (ethical and religious) purpose ; and he did it as following out the work of Locke in the spirit of Newton. If Locke, Berkeley and Hume are a series representing the natural development of English philosophical thinking at the time, Locke, Berkeley and Hartley are another series representing a movement of psychological inquiry then begun and destined to become ever broader and deeper. And the second series is certainly not the least important when we look beyond the century to what followed. The most characteristic English work of the later time has been done in the track of Hartley rather than of Hume. This is true even of the work, not psychological, of the younger Mill, who, though he presented as a logical theory of positive science a doctrine allied to Hume's negative philosophy, did not borrow it from Hume, but rather worked it out independently as the proper philo- sophical complement to the psychology of Hartley and his father, Hartley's close adherent. It is still more true of the psychological work of the so-called Associationists, James Mill and his successors, whether of the straiter sect of in- dividualists, or of the broader persuasion inspired with the doctrine of evolution. The note of English psychology thus far has been the study of mental phenomena in relation with physiological conditions (wherever these can be made manifest), and this without express metaphysical assumption, or even to the exclusion of metaphysical assumption, as in the positive sciences generally, whose advance has depended on their being thus pursued. To Hartley, more than any other, it is due that the science of mind has been brought (on the side on which it can be brought) into relation with physiology, and it is too little recognised with what extra- ordinary insight he anticipated some of the most important results now established in physiological psychology ; while, if ENGLISH THOUGHT IN THE EIGHTEENTH CENTURY. 197 it cannot be equally said that he steered clear of metaphysical assumptions at the beginning, it may be affirmed that his positive doctrine of mental acquisition is developed without the least reference to them. To speak of him as Mr. Stephen does, as a materialist, because he takes account of physical conditions throughout, is no more fitting than it would be to use the same term of any scientific psychologist of the present time ; or, if he is so described because he supposed the con- sciousness of the individual to result wholly from a grouping of incidental experiences, the term is no more applicable to him than to Locke. Curiously incoherent as are the parts of his general philosophic system (if philosophic it can be called), his psychology stands as one of the most remarkable in- tellectual productions of the eighteenth century, destined later, if not at the time, to have the deepest influence upon ' English Thought '. Passing now to the Moralists, we find Mr. Stephen's exposition guided by one main conception. So long, he maintains, as theology was a vital belief in the world and preserved a sufficient infusion of the anthropomorphic element, it affor.ded a complete and satisfactory answer to the common questions of ethics — what is meant by ' ought ' and 'goodness' and what are the motives that induce us to be good. Nor did the inquiry into the nature of our moral sentiments naturally suggest itself ; the only moral inquiry likely to flourish was casuistry, or the discussion as to the details of that legal code whose origin and sanctions were abundantly clear. But wider speculations as to morality inevitably occurred as soon as the vision of God became faint. It was growing faint in the seventeenth century when Hobbes could venture to put the bold questions he did. It had become so faint in the eighteenth century that men stood in face of a strictly practical issue : How was morality to survive theology ? Hence the outburst of ethical inquiry by such a multitude of thinkers. Mr. Stephen ranges them under three main heads : (1) the Intellectual School of Clarke, Wollaston and Price ; (2) the Common Sense School of Butler, Hutcheson and Beid ; (3) the Utilitarian School, founded on Locke and comprehending such different repre- sentatives as Hume, Waterland, Tucker and Paley. Shaftes- 198 ENGLISH THOUGHT IN THE EIGHTEENTH CENTURY. bury and Mandeville are at the same time treated incidentally at considerable length, as representing extreme phases of the recoil from the abstract metaphysics of the intellectualists ; and a separate section is further given to Hartley and Adam Smith, because of their different attempts to trace the psy- chological genesis or derivation of the moral faculty in man. In these ethical sections, Mr. Stephen never loses his hold upon the reader's attention, and not seldom he appears, perhaps, at his best both as a writer and as a philosophical critic. Especially when he has to deal with Hume, the exposition becomes masterly, and there is a very striking argument against looking for the root of morality in such an individualistic psychology as that beyond which all Hume's acuteness never carried him. Mr. Stephen's way of putting the alternative position is to say that the ethical problem cannot be solved except on the basis of a scientific sociology, but, whether called sociology or a truer psychology that refuses to look at the mental development of the individual apart from the social medium into which he is born, the basis is that which must be chosen by any clear-sighted experientialist at the present day. After Hume, the thinker who here as a moralist, or elsewhere as a philosophic theologian, receives most worthy appreciation from Mr. Stephen, is Butler. The serious, not to say sombre, mood of the man, oppressed with a sense of the dire reality of existence in an optimistic age, strikes a sympathetic chord in the mind of his critic, and evokes a response whose strength is hardly weakened by their speculative difference of opinion as to the supernatural. Of Mr. Stephen's other estimates, that of Samuel Clarke is among the most successful. Like Butler, Clarke falls to be treated at two places in his different characters of theologian and moralist, and both must be consulted for the judgment of him in either capacity. Mr. Stephen compares him, by a very happy "inspiration, to another famous Cambridge doctor, better known in these days but not more prominent, as an intellectual figure than Clarke was in his time — namely, Whewell. Clarke's distinction, while bred under English conditions and holding in great part by native authorities in science and philosophy, was that he had drunk also at foreign springs, and knew at once how far it became an ENGLISH THOUGHT IN THE EIGHTEENTH CENTURY. 199 English theologian to go with outlandish speculative philo- sophers and when it was necessary to stop or even to lift up his voice against their wayward aberrations. Mr. Stephen rather overstates his dependence on Descartes, or overlooks his dependence on Newton and his relation to Locke. There is also some want of precision in the passage referred to (vol. i. p. 119), where Leibniz is specially named as the thinker to whom Clarke stood " in the same sort of relation which Whewell occupied to modern German philosophers " (mean- ing Kant). But, all the same, the comparison remains a very felicitous one, and the remark which follows, that " in softening the foreign doctrines to suit English tastes he succeeds in enervating them without making them substanti- ally more reasonable," while throwing a real light upon Clarke, is a good instance of Mr. Stephen's power, displayed throughout his volumes, of dropping observations that strike home in regard to thinkers not so far removed as those of the eighteenth century. However, as a history of ethical speculation in England at the time, Mr. Stephen's review of the moralists strikes one as defective in several ways. No explanation is offered of the remarkable fact that the philosophical activity of the English mind was directed so predominantly into the line of ethical speculation, not slackening here even when about the middle of the century intellectual speculation was struck with sudden collapse. The review is also too abruptly ended and is more abruptly begun ; in particular, no attempt being made at the beginning to show the relation in which the different ethical efforts of the eighteenth century stood to earlier English efforts in the seventeenth. Again by class- ing together under the one head of ' Utilitarians,' moralists so different as Hume on the one hand, and Locke, Waterland, Tucker and Paley on the other, the common prejudice against Utilitarianism, as. if it were a system of selfishness, tends to be confirmed. And the principle itself which guides the whole exposition — that the philosophical inquiry into the grounds of right action was determined by the weakening of the reli- gious sanction — seems to come short of expressing the facts, both first and last, or even is rather obviously at variance with some of them. 200 ENGLISH THOUGHT IN THE EIGHTEENTH CENTURY. The strong point of the English mind in theoretical philosophy, as Mr. Stephen remarks early in his work, is its vigorous grasp of facts, its weakness is its comparative indifference to logical symmetry. Not less characteristic has been the English habit of thinking always with some view to practice, and making the theory of practice its chief philoso- phical concern. Far back in the days of the Middle Age, when the Church drew to itself the intellectual service of all the western peoples, and there was but one philosophy — Christian and European, the national tendency above all things to moralise already betrayed itself in English School- men like John of Salisbury, and Koger Bacon anticipated that conception of knowledge as subservient to human practice which another Bacon is supposed to have first disclosed to the world.1 The later utterance by Francis Bacon, coincid- ing with the beginning of the modern era of philosophical thought when the nations each went their own way, was indeed so peculiarly impressive that his countrymen are not unnaturally thought to have been ever since bound by its spell ; but it is nearer the truth to see in the great preacher of Induction only the representative for the time of the national habit of thinking. Hobbes, who owed nothing to Bacon, and took nothing from him, was not less practically minded in his deductive speculations, having never absent from his view the regulation of human conduct in society even when dealing with the most general aspects of know- ledge. Nor was Locke, who owed no more to Hobbes than Hobbes to Bacon, but with sturdy originality worked out his inquiry into human knowledge as an English counterpiece to the Cartesian philosophy reigning abroad, a whit behind either in his recognition of morality as " the proper science and business of mankind in general," while the useful arts should be the concern of special experts in default of a " scientifical knowledge " of nature not to be attained by human faculties. Berkeley, again, speculated with a moral or religious, at all events a directly practical, object in view ; and Hume's Moral Philosophy remains the most serious, as 1 The relation of the later to -the earlier Bacon is shortly .but effectively indicated in the introductory Lecture delivered by Prof. Adamson at Owens College in October last : Roger Bacon ; the Philosophy of Science in the Middle Ages (Manchester: Cornish, 1876). ENGLISH THOUGHT IN THE EIGHTEENTH CENTURY. 201 by himself it was the most cherished, of his achievements. What a moralising vein pervades the general literature of our country, to the sacrifice of artistic aim, has not seldom been remarked, though it has never been more forcibly exhibited than by Mr. Stephen himself in describing the literary activity proper of the period. It is intelligible, then, or at least it is not surprising, how varied and constantly renewed should have been the attempts by English thinkers of the eighteenth century, smaller as well as greater, to determine the reason and aims of human conduct, and how they should have been continued at a time when abstract metaphysical inquiry became paralysed ; more especially since the psychological impulse, which has told so markedly on the development of ethical thought in England, went on as we have seen steadily gathering strength, unaffected if not reinforced by the circumstances of the philosophical dead-block. With such a determination of the English mind towards practical philosophy, even as exhibited in the eighteenth cen- tury only, it is in any case hardly to be expected that then for the first time ethical inquiry should all of a sudden begin ; and yet this, it must be said, is the rather misleading impression given by Mr. Stephen's chapter on the moralists. It is true he alludes at starting to Hobbes's bold speculations on morality launched in the middle of the previous century, but he does not suggest, as in the interest of historical under- standing he might even have impressed, the fact that some of the most characteristic ethical positions of the later time were already taken up at the earlier. For example, the so- called Intellectual School of Clarke, Wollaston, and Price (of which, by the way, the shortcomings are much more effectively exposed than its serious scientific import is acknowledged) is treated without any reference to Cudworth ; though Cudworth, besides enunciating all the most dis- tinctive doctrines of the school — as Price, by borrowing wholesale from him rather than from Clarke, allows — was the author even of the "magniloquent trick of language about tbfi eternal and immutable nature of things " which Mr. Stephen declares to be the sole relic that survived its decay. It is also a real omission, in tracing the origin of 202 ENGLISH THOUGHT IN THE EIGHTEENTH CENTURY. Utilitarianism, whether in its stricter sense or in the looser sense of Hedonism adopted in the heading of Mr. Stephen's section, to make no reference to Cumberland, who has been not untruly described as the first philosophical moralist that appeared in this country, and who certainly did (to whatever dreary extent) reason about the grounds of human conduct in the spirit considered most essentially English. If a period is to be understood historically, it must not be taken too strictly, at least a parte prce ; and unfortunately it is just in dealing with the moral philosophers that Mr. Stephen confines himself with exceptional rigour to his century, thereby not a little reducing the value of the very part of his work that otherwise comes nearest to fulfilling the conditions of a history of philosophical thought. It is impossible also not to regret the confusion caused by classing under the one head of Utilitarianism all those moralists who in any way make the rule of right dependent on the promotion of happiness. Of course, this use of the term may be justified, because, in strictness, it applies equally to the selfish pursuit of one's own happiness and to the conscious regard for the good of all ; but nobody knows better than Mr. Stephen, or indeed has better set forth on the whole, the distinctive character of that ethical view which was lifted at once into importance by the genius of Hume, and has later become so identified with the English name in practical philosophy. Neither in a theoretic nor in any other point of view is justice done to Hume's serious attempt to find a rational explanation of morality when he is ranked with theological moralists like Waterland, who solves all difficulties by direct resort to the supernatural sanction, or even with Locke, who in a more round-about and uncertain way has recourse to the same constraining authority. How greatly concerned Hume was to prove the natural existence in man of altruistic sentiments is so clearly apprehended and plainly set forth by Mr. Stephen, that from him at least we have a right to expect no such indiscriminate classing as may tend to obscure the most fundamental distinction. Not only, however, is the loose classification made, but, in his eagerness to show how much better the system of altruistic (but dependent) morality can now be ENGLISH THOUGHT IN THE EIGHTEENTH CENTURY. 203 based, we find Mr. Stephen carried to the length of com- mitting an injustice. When he says that " later writers of the Benthamist school generally show a reluctance, as did Bentham himself, to admit the possibility of a perfectly disinterested emotion " (ii. p. 105), he says what it would be difficult to make good of any later utilitarian of philosophical standing. And speaking of Bentham, it is surely by an arbitrary exclusion that the author of the Principles of Morals and Legislation (written before the year 1780) is referred to the present century. Though there is truth in the remark that "the history of Utilitarianism, as an active force," belongs to the nineteenth century, at least as regards civil legislation, yet nothing is more characteristic of the history of English thought in the eighteenth century, than that in the last generation of it there should have been formulated those principles of public arid private right of which so revolutionary an application was destined in time to be made. Nor if it should be granted that Beritham's utili- tarianism, as an attempt to base morality upon observation, reduces it " to a mere chaos of empirical doctrines," as much as Hume's, is this anything but a reason for associating it with the work of the eighteenth century. There would be more reason, indeed, from Mr. Stephen's point of view, in referring even the younger Mill to the eighteenth, than in taking the opposite course with his great master in politics and morals. A few remarks, in conclusion, seemed called for on that conception which, if it can hardly be said in fact to guide, yet stands in the front of Mr. Stephen's treatment of the moral philosophers. Were the manifold ethical theories that sprang up in the century all so many attempts to find a secular rule of human conduct in default of the decayed or decaying influence of theological precepts ? The notion undoubtedly fits some of the facts and involves a general truth. Ethics, so prominent a department of the ancient philosophical systems, was of all the more obvious subjects of rational speculation the least cultivated when, after the long centuries of faith without thinking, the Christian doctors of the Middle Age began to think about their faith. Not that the practical rule of life was made a matter of no 204 ENGLISH THOUGHT IN THE EIGHTEENTH CENTURY. concern ; but it had been provided so expressly by super- natural authority that there could be no question except as to how it should be applied in the varying circumstances of the human lot. Hence all such reasoning as there was about human conduct assumed the form and the name of Moral Theology, while the complementary doctrine of Natu- ral Theology was but a part, however large, of the theoretic philosophy of the time. Theology stood for the whole of practical philosophy ; and thus in no direction — not even that of positive physical science — could the modern spirit, when it awoke, break away more decisively from the bondage of scholasticism than by entering on the path of ethical inquiry. Every great ethical system that has since been given to the world has truly been an attempt to find a strictly rational law of conduct. Such were the systems of Spinoza and Kant, and such also was the system of Hume. Such even, as Mr. Stephen might fairly contend, was the character of some of the minor ethical doctrines which he passes under review. But hardly will his reader carry away the impression that the English moralists of the eighteenth century generally had reached the stage of philosophical detachment from the old theological basis. Had the " vision of God " become faint in Butler — Butler to whom conscience was truly the voice of a supernatural judge, and whose psychology was the controversial buttress of his ethics rather than its philosophical foundation? Was Clarke the less a Schoolman in spirit because he lived in the days of Newton, and affected the form of scientific demonstration ? Or was Paley satisfied that the truth should be told without the fear of hell and the hope of heaven? Mr. Stephen must drop out of view all but two or three of his English moralists before he can see in the eighteenth century the clear begin- nings of that determined search for a naturalistic ground of ethics which is being pursued in the nineteenth, but not even now is admitted without protest and resistance. The truth, perhaps, is that Mr. Stephen, who is always as much a critic as an historian and, what is more, a critical thinker anxiously concerned about the speculative issues of his own time, has been somewhat over-ready to see the present in the past, and to reckon with the long departed as ENGLISH THOUGHT IN THE EIGHTEENTH CENTURY. 205 if they were adversaries or allies. This fault, if it is one, he can best expiate by writing another work, that not only will give better scope for the exercise of his special faculty but will be the more valuable according as he gives it free play and does not scruple, while tracing the currents of opinion, to direct them to the utmost of his power. Let him give us that critical History of English Thought in the Nineteenth Century which the very defects as well as the excellences of his present volumes mark him out as signally able to essay. THE PHYSICAL BASIS OF MIND.1 UNDEE this title Mr. Lewes, in his new volume,2 passes from the general part of his philosophical task to deal with the more special ' Problems of Life and Mind,' and delivers himself on various questions that have lately engrossed much attention. Prominent among these is the question of so- called Animal Automatism, and it is proposed in the following pages to offer some remarks on the subject after considering his handling of it ; but first it is necessary, as well as due to Mr. Lewes, to take account of other parts of the volume, which contain the results of long-protracted inquiry. In this country at least, Mr. Lewes holds an almost unique position. He is a philosophical thinker and psycho- logical inquirer who is also a practical worker in physiology ; or he is a physiologist whose positive investigations of the innermost phenomena of organic life are guided by trained psychological insight and an ever-present regard to philoso- phical principles. In either aspect of it, his activity is of prime interest to all who at this present time are concerned about the problems of Life and Mind. Physiological special- ists, who naturally are every day more and more encroaching on the psychological domain, may draw much enlightenment from one who knows how to speak their language as well as the other ; and psychologists, who have to endure many a sneer for their readiness to eke out subjective observation with second-hand objective discoveries, may repose special confidence in a fellow-inquirer who accepts no physiological results that he does not himself verify. Those parts, there- fore, of his present volume where he appears most distinctly 1 Mind, iii. 24. - The Physical Basis of Mind, with illustrations. Being the Second Series of Problems of Life and Mind, by GEORGE HENRY LEWES. London: Triibner & Co., 1877. (Vol. i. of the First Series, The Foundations of a Creed, appeared in 1874, and vol. ii. in 1875.) THE PHYSICAL BASIS OF MIND. 207 in his double character of physiologist and psychologist, or prepares the way for assuming it, have the strongest claim on our attention here. A short preliminary survey of the volume will make plain what they are. We have first a series of discussions on ' The Nature of Life'. Since it is animal organisms that manifest mind, a clear view of the distinctive character of vital organisation is naturally the primary requisite for understanding that special form of life which mind is. Towards the general argument of his volume, Mr. Lewes here more especially contends that no mechanical expression can ever adequately represent the processes of life ; he also impresses, for use later on, the very important distinction between Property and Function which he had the credit, nearly twenty years ago, of first bringing clearly into view in the physiological science of the present generation. The consideration of vital phenomena is then brought to a close in a long chapter on Evolution, which aims at showing that a struggle for existence is maintained not only among organisms but also among their component tissues and organs, and that the unity of type in organisms is rather to be explained by all- pervading laws of Organic Affinity than by Mr. Darwin's supposition of Unity of Descent. The next section is con- cerned with ' The Nervous Mechanism,' and contains much destructive criticism of current scientific doctrines, followed up by an exposition of such general notions of the structure and action of the nervous system as the author believes can be affirmed in the present imperfect state of knowledge. Then follows, under the heading of ' Animal Automatism,' a somewhat varied collection of dissertations — historical, abstract, polemical — directed to the assertion of " the bio- logical point of view" against a purely mechanical one in treating of mind as related to the living organism. And last, within the present volume, ' The Reflex Theory,' which forms so great a part of the prevalent doctrine of neuro- physiology, is subjected to an elaborate consideration from the same " biological " point of view, taken as it had already been by the author in regard to this particular question when he wrote his well-known popular work The Physiology of Common Life. 208 THE PHYSICAL BASIS OF MIND. The last two "problems," while intimately connected, arise naturally out of the "problem" of the Nervous Mechanism as treated by Mr. Lewes, and must be ap- proached through it. On the other hand, the preliminary dis- cussion on the Nature of Life, if its general import is kept in view later on, need not here detain us. Not the least interesting portion, it may only be remarked in passing, is that in which Mr. Lewes seeks to generalise the principle of Natural Selection by extending it to the organised elements of composite animal organisations ; as he had already some years ago proposed to amend Mr. Darwin's theory in another direction, namely, by supposing Natural Selection to proceed upon an indefinite number of original protoplasts emerging under similar conditions, instead of the four or five or even one considered by Mr. Darwin himself at once necessary and sufficient to account for all the variety of related organic forms. Mr. Darwin, in reply to the earlier criticism, has admitted (Origin of Species, 6th ed., p. 425) the possibility that at the first commencement of life many different forms were evolved, but thinks it may be concluded that in that case only a very few have left modified descendants. One would gladly learn his opinion of the extension now proposed of his famous theory. Perhaps it may be guessed that he would decline to load the theory with an application so purely speculative, and not unreasonably, considering the difficulty of its verification even within the original limits. It cannot, however, be denied, in view of what is already known of the composition of organisms from living elements, that the question of the origin of species is but one aspect of the general question as to the development of life, and Mr. Lewes does good philosophical work when he raises it in its full implication. As regards the Nervous Mechanism, Mr. Lewes has long been known to hold unfashionable opinions, which now at last receive a formal expression. He confines himself for the present, indeed, to the more general aspects of the nervous system, reserving the question of the functions of the brain till the physiological exposition can be accompanied by the necessary survey of psychological processes ; but, as it stands, his treatment is fraught with observations of deep THE PHYSICAL BASIS OF MIND. 209 import to the psychologist. Mr. Lewes is persuaded that a great part of the current doctrine, confidently propounded by anatomists and physiologists and implicitly received by too confiding psychological inquirers, is either wholly base- less or at least not yet based on actual experience. An imaginary anatomy makes fibres run into cells and cells prolong themselves as fibres in a way that no eye has ever seen, all because of a physiological prepossession as to the part played by these particular elements in the nervous system. It is by an over-simplification of the system that these elements are singled out from the whole mass of it, and the proper scientific task of analysis is again overdone when division is arbitrarily made of the system into sides and parts, which are credited with such diverse characters in separation that it becomes impossible to understand how they should form together a system the most coherent and uniform that is. It is difficult not to allow the force' of Mr. Lewes's objections against many of the most fundamental positions in the reigning doctrine of neuro-physiology, a.nd the vigour of his criticism, informed as it is by the practice of original experimental work, bespeaks attention to the doctrine (given in outline) which he would substitute, at least provisionally, for the too definite teaching of the schools. Some of his more characteristic views, not now expressed for the first time, have indeed already begun to modify the traditional dogma in the minds of younger physiologists. The key-note of his doctrine is the assertion of uniformity of structural plan and mode of working in all parts of the nervous system, high and low. This is not denied, or is even affirmed, in so many words, by physiologists in general, but they are apt to couple any such assertion with others which to Mr. Lewes seem to rob it of all its significance — as, for instance, that the action of the lower centres is purely reflex or mechanical ; that the action of the higher centres differs in being conscious action ; that particular nerve-cells are sensory or motor, or even sensational, or ideational, or emotional ; and the like. Not that he either pretends that there is no distinction in the action of the different parts ; there is undoubtedly the most marked difference of function 14 210 THE PHYSICAL BASIS OF MIND. or use, according as the various collections of nervous ele- ments, distinguished as particular nerves or centres, are connected with different structures in the bodily organism. But this circumstance only makes it the more vitally important, for the comprehension of the system generally, to signalise the fundamental identity of character pervading all its parts, and this Mr. Lewes does by distinguishing (after Bichat) Property from Function, and maintaining that the elements of the system in all their variety, both as elements and when aggregated, manifest everywhere one perfectly characteristic property. This property he speaks of under the two names of " Neurility " and " Sensibility," according as it is presented by the nervous lines brandling out towards the periphery or by the parts distinguished as central ; but, however named, we are to think of a purely objective quality, symbolising a multitude of changes ex- pressible ultimately only in terms of motion. Thus under- stood, the conception undoubtedly helps to a clear under- standing of the whole system of neural processes, which is otherwise apt to be misconceived from the fact that our conscious mental life is obviously related to some of the processes rather than to others, or to some more than to others. There is, besides, positive evidence that native property survives functional appropriation in the well-known facts, established by Vulpian and others, of function becom- ing experimentally reversed ; and Mr. Lewes would even suggest in one place (p. 282) that the same fibres which carry impulse out to the muscles may transmit the muscular reaction as a recurrent stimulus inwards to the centres — a view which, if it could be maintained, would help to recon- cile the notoriously opposite interpretations of the muscular sense now prevalent. He also gives due prominence to all the facts tending to show that nerve-fibres are not merely passive carriers, and that the grey matter (for example, in the spinal cord) performs the work of transmission as well as any fibres. Next to the fundamental uniformity of plan and process throughout the nervous system, it is the actual coherence and solidarity of its parts with unity of action that Mr. Lewes is most concerned to establish against the exagger- THE PHYSICAL BASIS OF MIND. 211 ated " analysis " of the common physiological view. He objects to the distinction of peripheral and central parts as artificial, protests against the opposition of sensation and motion if taken to imply the independent arid unrelated working of two sides in 'the nervous system, and seeks above all to bring into relief the diffuse character which nervous disturbance is prone to assume with the effect of implicating the whole organism. He does not, of course, overlook the salient feature of the nervous system known as "isolated conduction," or forget how mental growth through experience depends upon restriction of the original " irradiation " ; but he is utterly sceptical as to the efficiency of the medullary sheath which is commonly assigned as the means of insulating the ultimate nerve-lines, while refusing, in the present state of knowledge or ignorance, to hazard any other explanation of the fact in as far as it occurs. That it must not be asserted in any absolute sense, so as to imply fixity or invariability of nervous conduction, he is quite sure : " fluctuation," he is never tired of repeating, is the characteristic at least of central combinations, and this, he more than suggests, may be dependent on the presence of a structural element for which no allowance has been made in the current physiological theories, namely, the so-called Neuroglia. According to some a kind of merely connective tissue, affording mechanical support to the true (fibrous and cellular) elements of the nervous system while itself not neural, this "nerve-cement" seems to Mr. Lewes, whether called neural or not, to play an essential part in all the processes of the system and probably a more important part than even the nerve-cells (p. 246). : In any case, until the network of the Neuroglia is better understood and duly taken into account, there can, he maintains, be no thought of having a theory of the working of the nervous system 1 Wundt (PhyKi.nl. Pxj/c/Jo/o//7>, p. 29), after a short anatomical descrip- tion of the Neuroglia in liis text, disposes of it physiologically in a foot- note. He mentions that the body of it, while enclosing cells that are clearly not nervous, has itself a constitution somewhat resembling the protoplasmic contents of ganglionic cells, and that many ob-ervers (Wagner, Henle, &c.) have thereby been induced to consider it as nervous in character. But this view, he declares, is wholly at variance with all that is known of the relations subsisting between the fundamental nerve- elements, viz., the ganglionic cells and nerve-fibres. 212 THE PHYSICAL BASIS OP MIND. satisfactorily based, as it should be, on the ground of ele- mentary anatomy. Meanwhile Psychology, in the way of objective help, must be content with such general know- ledge as anatomy already affords of continuity and coherence in the nervous system, and for a notion of the physical con- ditions of mental life must rely rather upon the researches of physiologists and pathologists. The general representation of the working of the nervous mechanism which Mr. Lewes accordingly proceeds to give at the end of this part of his inquiry, strikes one as marked by a happy mixture of boldness and circumspection. It is, of course, only provisional as well as general, but the way in which he manages, by a comparatively simple theory, to order the chief facts and to suggest consistent explana- tion of special difficulties, deserves warm acknowledgment. Without following him into his formal expression of laws, some notion may here be given of his view of nervous action by quoting a passage that brings its main points into relief through an apt and instructive simile : — " Imagine all the nerve-centres to be a connected group of bells varying in size. Every agitation of the connecting wire will more or less agitate all the bells ; but since some are heavier than others and some of the cranks less movable, there will be many vibrations of the wire which will cause some bells to sound, others simply to oscillate without sounding, and others not sensibly to oscillate. Even some of the lighter bells will not ring if any external pressiire arrests them ; or if the ? are already ringing, the added impulse, not being rhythmically timed, will arrest the ringing. So the stimulus of a sensory nerve agitates its C' n',re, and through it the whole system ; usually the stimulation is n aialy reflected on the group of muscles innervated from that centre because this is the readiest path of discharge ; but it sometimes does not mainly discharge along this path, the line of least resistance lying in another direction ; and the discharge never takes place without also irradiating upwards and downwards through the central tissue. Thus irradiated, it falls into the general stream of neural processes ; and according to the state in which the various centres are at the moment it modifies their activity " (p. 284). A notable feature in this view is the treatment of Arrest as but another aspect of Discharge, whereby he gets rid of the complex machinery of inhibitory centres which has become so troublesome in recent physiological theory ; but instead of dwelling on this or any other of the interesting questions raised by Mr. Lewes, it must suffice to direct the attention of psychological students to the whole of this closing chapter on the Laws of Nervous Activity, and we THE PHYSICAL BASIS OF MIND. 213 may now pass to the third and fourth "problems". Thus far Mr. Lewes has been treating the nervous system from the anatomical and physiological point of view. Only in the chapter where he introduces his use of the word Sensibility to mark the common property of nerve-centres (as opposed to the common property of peripheral nerves, which he calls Neurility) is he led to refer to the subjective aspect of nerve- processes which, he does not deny, is. unavoidably suggested by the word. In spite of the ambiguity he deliberately makes choice of it to designate the objective quality he has in view, and he believes he has his reward in evading, with it and its companion-term Neurility, the more seriously confusing associations of the alternative name Nerve-force. For the subjective aspect of Sensibility he proposes, or rather at once claims as a matter of course, to use the word " Sentience " ; and, though in the chapter itself he somewhat curiously interchanges the words as if they meant not only the same thing in different aspects (which he afterwards seeks to prove) but quite the same (subjective) aspect of the thing, yet, on the question of principle, he is most impressive in his distinction of the two aspects, and, while indicating as clearly as possible the respective tasks of physiologist and psychologist in the matter, he confines himself in all the remaining chapters of his second part strictly to the objective view. In the last two parts of the volume, on the other hand, it is the subjective phase of mind that is uppermost — not indeed as viewed in itself by the introspective psycho- logist but (in accordance with his main title) as that of which the nervous mechanism is the " physical basis ". The amount of controversial matter in these two parts makes it somewhat difficult to take an orderly critical survey of his positions. On the whole it seems best to work into his meaning through the discussion of the Reflex Theory which he himself takes last, 'keeping in view, where necessary, the more general considerations ranged under the head of Animal Automatism. What is the precise import of the Reflex Theory as under- stood by physiologists, who do not as a rule trouble them- selves much about the full psychological implication of their statements, — may be a matter of question ; but Mr. Lewes 214 THE PHYSICAL BASIS OF MIND. takes pains to leave us in no doubt as to the counter-theory which he, with his face distinctly set towards psychology, would substitute for it. While the current theory seems to him to assert dogmatically that the nervous processes in lower centres may and do pass as purely physical (or, as they are called, mechanical) changes without having any psychical aspect whatever, he contends that every central nervous process, to the very lowest and simplest, in any organism, intact or truncated, that is not dead, has in and for itself its proper psychical phase or aspect, as much as the highest and most complex cerebral process accompanying or accompanied by that which all understand as a conscious experience. He does not say that the psychical state con- comitant with the action of a lower centre is a conscious state — either that the centre is itself endowed with con- sciousness or that the man or animal is conscious in the case ; as indeed, for that matter, he denies that the centres immediately concerned in the higher cerebral process are in themselves the seat of consciousness, or that the man or animal need always be conscious in this case. But he does assert that in the one case as well as the other there is, besides the physical, a real psychical occurrence which is to be understood in terms of "Feeling" or subjective ex- perience. He commits himself, for example, to the general statement that " Feeling is necessary for reflex action " (p. 435), meaning this at all events, that whenever and wherever a central nervous process goes forward in a living organism there always is present something that may be called Feeling. His favourite expression, however, is that the centre has Sensibility ; and, though he may have wished elsewhere to understand by Sensibility a purely physical or objective process — something wholly expressible in terms of matter and motion — here, there can be no doubt, he means by Sensibility a subjective condition as well. This is abun- dantly clear when, in the course of his argument, he claims for every active centre a power of Discrimination, Memory, &c. ; or if it be said, as is sometimes half implied (p. 463), that these terms may after all be understood objectively — e.g., Discrimination as meaning only " neural grouping" — cadit quaestio. No upholder of the Reflex Theory, even THE PHYSICAL BASIS OF MIND. 215 in Mr. Lewes s statement of it, denies that the centres perform a work of neural grouping, or that, as a plain matter of objective fact, there does appear an " adaptation of the mechanism to varying impulses ". The theory he opposes has, according to Mr. Lewes, nothing to rest on but a mere prejudice as to the brain alone being the seat of sensation. When the actual facts observable in animals (with or without brains) are fairly weighed, especially in the light of what is known of the structure and laws of the nervous system, the theory must give way to a truer repre- sentation of the behaviour of the living organism. Presump- tion against presumption, it is quite the opposite view that is suggested by way of general deduction before looking at the particular evidence. The nervous system, as we saw, has a uniformity of structure and working everywhere, and is also in the truest sense a coherent whole. In as far as it is possible at all to speak of separate action of its parts (this or that centre) in their natural state of union, the processes in all of them appear exactly similar ; and, in fact, a process set up anywhere may always implicate the whole system, and through this the organism generally. A reaction of the general organ- ism being the natural outcome of every stimulus, the particular reaction that is at the moment possible for each, amid the multitude of impressions always being received, will determine the character it assumes subjectively. The same kind of impression that at one time appears as a conscious state specially attended to or distinctly felt, may at another time in the crush of impressions not come into consciousness at all ; but in being thus unconscious, it does not cease to be sub- jectively— it does not lapse out of the domain of Feeling, for at any moment it may again acquire the character of a conscious sensation, if the brain is not otherwise engrossed. So, if the brain is removed altogether without loss of life, we are not to suppose that such reaction as is still possible in the organism has no longer any psychical character, merely because it can no longer appear as it did to the animal that was conscious through the brain. Indeed, if we turn to the actual facts, " instead of marvelling at the disappearance of so many modes of sensibility when the brain is removed, our surprise should rather be to find so many evidences of THE PHYSICAL BASIS OF MIND. sensibility after so profound a mutilation of the organism " (p. 439). The facts warrant, according to Mr. Lewes — especially those placed under the head of Instinct (pp. 463 ff.) — precisely the same kind of inference as is forced upon an observer by the deportment of animals in their intact state. With Pfluger, he urges that it is only by inference from objective signs that we ascribe subjective life to any other man or animal, and where the signs, though in the absence of the brain, remain precisely what they were, the inference is not to be evaded. There is no need to follow Mr. Lewes into his interpreta- tion of the facts, as far as he adduces them, in detail. The point of real significance is to understand the general reason why Sensibility in its full meaning — not as mere " Neural grouping " — should be so expressly claimed for the spinal cord. Or it may be said that everything depends on the use to be made of the concession, supposing it were not with- held ; for if it is true that the claim can never be proved, it is equally true that it admits of no positive disproof. First, however, we must seek out the true meaning of the Reflex Theory, to see what is the real difference that separates Mr. Lewes and its upholders. The Reflex Theory, though often enunciated in an in- cautious or in a half-hearted way, is at bottom nothing but an assertion that, wherever there is nervous stimulation followed by nervous outcome (appearing as movement or otherwise), there is a continuous physical process through the central parts involved, and no hyperphysical or meta- physical agency is to be assumed there for the explanation of the forthcoming result. When first formulated, the statement was confined to the lower centres, but this may have been rather because the processes in these were simple and could be approximately traced than because the cerebral processes were believed to be disparate in kind, that is to say, physically discontinuous, by reason of the intervention of a non-physical agent (the conscious ego) at the higher centres. Or, if indeed some, nay many, assertors of the Reflex Theory have limited it to the spinal column and more immediately connected parts, under some such notion (more or less vaguely expressed) of a difference of conditions in the THE PHYSICAL BASIS OF MIND. '217 brain, this is a weakness or misunderstanding which clearer heads have been able to surmount with the gradual advance of physiological knowledge. The doctrine of Animal Autom- atism, as Mr. Lewes himself remarks (p. 389), is only the Reflex Theory legitimately carried out ; at least, it includes the assertion that all central nervous processes whatever, high as well as low, are physically continuous — that the " nervous arc " is unbroken in the brain just as in the cord. When, therefore, Mr. Lewes urges elsewhere (p. 453), as one objection against the Reflex Theory, that there are cerebral reflexes as well as spinal reflexes, he urges that which consistent supporters of it are themselves most forward to maintain. He does not differ from them seriously even when he would urge that, as cerebral processes in another aspect of them are mental processes, so some kind of mental process may always be assumed as the obverse aspect of a spinal reflex : they do not assert this, but neither do they deny it as a matter of fact in what they do assert. He differs from them radically only if he maintains that Reflex Action is made what it is through the agency of Feeling — that " Feeling is necessary "for Reflex Action " in the sense that without the presence or interposition of feeling reflex action cannot be conceived as proceeding. Now it is impossible to doubt that this or something very like it is Mr. Lewes's meaning, and that he evidently thinks he thereby makes a distinct advance towards a scientific comprehension of Mind. This is the object he has in view throughout his whole argument, and not the gratification of any mere fancy for harmonious philosophical expression. Others have indulged in speculation as to an unconscious mental life bound up with the action of the spinal cord, and, not stopping there, have interpreted in an analogous manner the vital processes in plants and completed their philo- sophical sweep by supposing every change or motion in the physical world to be in some shadowy fashion the direct manifestation of a mind or mental principle. Mr. Lewes does not go so far a-field. He founds no argument on the so-called sensitiveness of plants, to say nothing of simpler physical processes ; he does not assert that wherever the property of Neurility is manifested, as in detached portions '218 THE PHYSICAL BASIS OF MIND. of nerve, there we must also assume the presence of some sort of subjective feeling ; nay, even when there is distinct " neural grouping," and thus evidence of the objective pro- perty of Sensibility, as when the cheek of a guillotined victim responds with blushing to a stroke, he scouts the notion of the blow being felt (p. 439). But wherever there is an animal organism, either living as it naturally lives or, however mutilated, able to retain life, all its central actions, he maintains, are what they are — actions of a living thing and not motions of a dead mechanism — only by virtue of Feeling, and if not first viewed as felt they are wholly unintelligible. What, then, is the precise difference between a Living Organism — at least an animal organism with a nervous system — and a mere Mechanism or Machine, which renders it necessary to assume feeling as the ground of all action in the former? This is a critical question which Mr. Lewes raises over and over again within his volume, and strives to answer in the most determinate way. His answer always turns more or less upon the point that an organism is peculiar in showing selective adaptation in all its acts, that is, varying combination of motor impulses to suit the varying requirements of the effect to be at any time pro- duced, or, as he also puts it, fluctuating combination of elements in response to variations of stimuli. This, he holds, is found in no machine ; nor has a machine either that primary constitution, distinctive of organisms, which appears as their inherited specific nature, or a history, in the sense of having its primitive adjustments modifiable through development of structure brought to pass by the very fact of its working experience. Otherwise, in his many discussions of the subject, he urges that, however organisms may exhibit phenomena referable to physical and chemical agencies, they also exhibit others that can never be ex- pressed in terms of these ; and, again, that the organism is no mere mechanism, because mechanics can assign only the abstract laws of its movements, and cannot account for its behaviour in the concrete. The statements may pass for what they are worth ; but even if they were unexceptionable — which the last, for THE PHYSICAL BASIS OF MIND. 219 example, hardly is, since mechanics gives no more than the abstract laws of the motion of any body whatever — they yet fail to prove anything as to the efficacy of Feeling in organic processes. It is accordingly by another line of argument* that Mr. Lewes really seeks to establish his general position. He does not so much build any conclusion on the short- comings of the Reflex Theory, as reject this because he has already satisfied himself that where conscious feeling is allowed by all to be present, it determines the nervous processes to be what they are in the living organism. Here, then, we turn expressly to his view of the doctrine of Animal Automatism. An outgrowth (in its recent statement at least) from the Reflex Theory, it may perhaps be so over- thrown as to uproot the Reflex Theory with it. Its central idea, now become familiar to all, is that consciousness, although present, does not count for anything in the vital history of man or animal — that all animal actions may be completely expressed and accounted for in terms of (nervous) matter and motion without the interposition of feeling as a factor at any point of the course and indeed without any reference whatever to conscious experience. Supposing this were true, there is obviously a very intelligible sense in which it can be said that everything proceeds mechanically in the living organism : not that there is no difference between a biological process and a simple physical move- ment, any more than there is no difference between a chemical reaction and the rebound of a ball, but in the sense that just as a chemical process can and must always be interpreted ultimately in terms of motion, so a nervous event must likewise in the end be so interpreted. Be this point of expression, however, as it may, Mr. Lewes is by no means disposed to grant the main position. He contests the ground inch by inch with Professor Huxley who some years ago gave an impressive exposition of the doctrine of • Automatism, and, what is more, he enters upon a line of consideration which not only, as it seems to him, affords the deepest reason for asserting Feeling to be an agent in the vital procedure of man or animal, but also yields a strictly psychological solution of the general question of the relation between Body and Mind. 220 THE PHYSICAL BASIS OF MIND. As a metaphysician, Mr. Lewes is a monist who declares that objective Motion and subjective Feeling are but two aspects of one and the same real, but he confesses that he did not always clearly see how a physical process could also be a psychical process. Even now, in a chapter (on Body and Mind) that is otherwise marked by great insight and subtlety of expression, there is some want of clearness or consistency in the explanation that is offered ; but his general drift is unmistakable and is to the effect that what we call Matter and Mind, Object and Subject, are symbols of different modes of feeling or sentience, which may both represent the same real, just as one tuning-fork may appear moving to the eye and sounding to the ear. The two differ merely in the mode of apprehension. Still, they do differ, and nobody could more impressively urge than does Mr. Lewes in this chapter (see especially p. 342, as at the earlier stage before referred to, p. 193), that there must be no mixing-up of the different aspects — that when we are talking in terms of Matter and Motion, i.e., " optico-tactical experi- ences accompanied by muscular experiences," we must not shift about and pass over into the phase of specially sub- jective experience for which the comprehensive symbol is Mind, nor vice versa. Thus, if by positing only a difference of psychological aspects, not a difference of substances, he is not saddled with the metaphysical difficulties of Dualism, he also, by taking the different aspects as equally independent, avoids the error of those who are prone to sacrifice the subjective to the objective aspect, speaking of the terms of the physical series as the causes of the corresponding psychi- cal terms in a sense which does not admit of being reversed — as if, that is to say, the one were always to be absolutely assumed, while the other may be considered or neglected at will. And yet he is perfectly aware of the special scientific advantage there is in seeking for an objective expression of the facts of subjective experience, which, though it never should be declared a mere accident of the series of physio- logical processes, does yet, as subjective, not admit of the same rigour of scientific statement. This, then, is the argument, and so far it might seem intended for the rescue of Feeling from the subordinate THE PHYSICAL BASIS OF MIND. 2*21 position to which it has too often been improperly consigned, and the establishment of a thorough-going parallelism of the physical and psychical ; but now we have to learn that Mr. Lewes's real meaning is very different. Because the objec- tive series of nervous processes and the subjective series of corresponding mental states may both, in ultimate psychological analysis, be regarded as modes of feeling in some consciousness or other, this is to be a reason for declaring that Feeling — meaning always a mental state in the subjective series — may and does enter as a term into the objective series, which, as properly objective, consists of molecular movements in nerve. Let the reader, in particular, refer to p. 403, where, after his long combat with Prof. Huxley, Mr. Lewes proceeds to sum up his argument on the special question of so-called Automatism. There we are reminded once again that, though we may believe Conscious- ness, which is a purely subjective process, to be objectively a neural process, we are nevertheless passing out of the region of physiology when we speak of Feeling determining Action : motion may determine motion, but feeling can only determine feeling. Yet we do, says Mr. Lewes, speak of Feeling determining Action, and we " are justified : for thereby we implicitly declare what Psychology explicitly teaches, namely, that these two widely different aspects, objective and subjective, are but the two faces of one and the same reality. It is thus indifferent whether we say a sensation is a neural process or a mental process — a mole- cular change in the nervous system or a change in Feeling. It is either and it is both." Certainly, it is here made clear why Mr. Lewes has previously permitted himself to use the same word Sensibility to express the objective fact of neural grouping and also a fact of subjective experience ; but with what reason he denounces those who, when they are speaking in terms of matter and motion, cannot keep to their text but will persist in dragging in terms of subjective import — is not so clear. Why should they not use the subjective words ? How do they go beyond the reckoning, when it is exactly the same thing they are speaking about in the one language or in the other? Or is Mr. Lewes's meaning this — that the physiologist indeed must keep, like 222 THE PHYSICAL BASIS OF MIND. any other physical inquirer, to the sphere of the objective in which he finds himself and which he cannot explain, but the psychologist is at liberty to pass at will between the sub- jective and the objective spheres because he knows and can prove them to be one in reality? If this be so, surely the psychologist's fate is hard. Alas for his insight if it must be the death of his science — if it shows him the same thing with two different sides to be named and will not suffer him to speak consistently about either ! Now let us note, before closing the account, two other positions taken by Mr. Lewes that are in different ways remarkable. One is where he declares at the end of his whole argument (p. 409), that "the question of Automatism may be summarily disposed of by a reference to the irre- sistible evidence each man carries in his own consciousness that his actions are frequently — even if not always — deter- mined by feelings. He is quite certain that he is not an automaton and that his feelings are not simply collateral products of his actions, without the power of modifying or originating them." And Mr. Lewes adds, " this fundamental fact cannot be displaced by any theoretical explanation of its factors ". One reads the words with a certain surprise. There may be reason indeed for protesting against such an incautious statement as that feelings are "products" of (nervous) actions : all that Mr. Lewes urges anywhere against attempting to explain the psychical series as de- pendent on the physical series, is much to the point. An Automatist who contends for pure parallelism of the physical and the mental, must no more think of breaking the mental line for the physical than the physical for the mental, nor has he a right to view the mental as a discontinuous efflux from the unbroken chain of nervous events. But the bare suggestion that any scientific deliverance on the subject can be based upon the immediate evidence of consciousness, is somewhat confounding when it comes from Mr. Lewes. The end of that kind of reference in questions of philosophy is but too well known. If it were allowed in this particular case, what becomes of the parallelism of aspects which nobody maintains more strongly or on deeper grounds than Mr. Lewes? He would break it in one direction as much THE PHYSICAL BASIS OF MIND. 223 as he charges Prof. Huxley with breaking it in the other. But, indeed, from the point of view of direct consciousness, what question is there of a parallelism at all? That a nervous process represents one purely phenomenal aspect of what, on another purely phenomenal aspect, is a conscious mental state, may be a very profound truth, but it never was ascertained on direct evidence of consciousness, which, in the sense in which it ever may be said to take account of nervous processes, views them as physical changes in a material structure supposed to exist apart. Nor, whatever reason or excuse there may be for the natural conviction we have as to a relation between feeling and bodily action, can this be allowed to affect one way or another the validity of the philosophical interpretation. The other statement referred to occurs at an earlier part of the argument, but is here taken last because it gives occasion for the few remarks on the doctrine of so-called Automatism which will bring this article to a close. Can we tianslate all psychological phenomena into mechanical terms ? asks Mr. Lewes at p. 352, and he replies (for reasons before mentioned) that we cannot — "nay, that we cannot even translate them all into physiological terms . . . nor can the laws of Mind be deduced from physiological pro- cesses, unless supplemented by and interpreted by psychical conditions individual and social". It is important to take account of this last remark (though it is not followed out at the place or anywhere adequately enforced throughout the discussion), because otherwise the denial of the possibility of expressing mental phenomena in phvsiological terms would stand in sharp contradiction with all that the author so often says about neural and mental processes. Plainly he can- not mean that there is not an exact physiological expression (if it could be obtained) for every psychological phenomenon. He rather means (I can only suppose) that just in the sense in which a biological phenomenon is more than a chemical one, so a psychological phenomenon is more than a biological. And this is a most important consideration, which if fully grasped may lead us to see that the notion of Automatism fails to express just that which is most characteristic in the life of Mind. But for this a little explanation is necessary. '224 THE PHYSICAL BASIS OF M-IND. It was said above that there is a sense in which the expression of biological phenomena in purely objective terms of motion may be called a mechanical view of them. Does this mean that from the principles of mechanics it is possible to deduce the phenomena of life? Not at all. It only means that, as life is manifested by a material structure, no vital change, when it happens, can be interpreted other- wise than as some more or less complex phenomenon of motion. More immediately, in many cases, the vital change may have to be phrased as a chemical process, but this, it is not denied, is a peculiar mode of motion — some re-arrange- ment, let us say, of atoms in space ; and mechanics (or general physics) contains the laws of all such change of position. Of course there is nothing absolute or final in such an expression of chemical and biological phenomena. Even supposing we could assign to the minutest particular all the motions or re-arrangements in space that constitute a chemical or a biological phenomenon — supposing, that is to say, we had found the complete physical or mechanical ex- pression— it would still remain a problem to find the purely mathematical expression of this physical expression ; and, again, the full mathematical expression, if it could be found, might be viewed as the result of a conceivable logical combination. But short of this last stage, at which the problem ceases to belong to objective science, it has come to be thought sufficient in modern times to find the mechanical expression for any material phenomenon, because motion admits of definite measurement ; and hence the idea that such an expression constitutes an ideal explanation. However, just as the laws of motion cannot themselves be deduced from mathematical principles without data from experience, so, I repeat, there is no question of merging chemistry or biology in physics, in seeking for a mechanical interpretation of chemical and vital phenomena. Chemical processes must be investigated in the special conditions under which they appear in our experience — only always in the light of physical principles ; vital processes likewise — only always in the light of physical and chemical principles. And so also mental phenomena, while studied in the light of biological principles and the others implied in these, have THE PHYSICAL BASIS OF MIND. 225 to be investigated in the special conditions that are found to determine them. They doubtless admit of translation into physiological terms, but physiology can never explain their rise. Now the doctrine -of Automatism declares that the state of the living organism, more particularly the nervous system, is at any moment the effect of its state immediately preceding and the cause of its state immediately succeeding; just as an automaton, or mechanism involving some internal principle of motion, goes through a series of operations each of which in turn brings on the next. As a matter of fact, the various nervous processes, as they are successively brought to pass, have or may have subjective concomitants, which are called, in the cases where they excite attention, states of conscious experience ; but none of these have the least real influence in determining the next condition of the organism, or (as it should be, but is not always, clearly understood and expressed) are themselves determined by the accompanying or the foregoing organic states — at least in the sense in which these are causally related to one another. Though the presence of consciousness makes the man or animal a conscious automaton, all the vital acts that are commonly called mental are, it is said, truly those of an automaton inasmuch as they are physically predetermined and would come to pass equally though consciousness were wholly absent. The doctrine is thus something more than a mere extension of the Reflex Theory, as it was previously described. As the name Automatism suggests, the organism is supposed to have within itself a principle of action whereby the succession of nervous processes, both cerebral and spinal, is physically determined ; and the direct implication is that the life of man or animal not only may be considered as a set of purely physical occurrences, but cannot otherwise be scientifically regarded. Now, if this is at all a true representation of the theory of Animal Automatism, it is surely quite inadequate as an expression of the facts of mental life. The state of the brain or whole nervous system at any moment is always one factor in the causation of its succeeding state, but, at least in all cases where anything of the nature of a new mental 15 226 THE PHYSICAL BASIS OF MIND. experience or acquisition is involved, it is one factor only. If we consider how many and what kind of factors may co- operate in producing the physiological condition (of brain, &c.) which corresponds with that which we call (subjectively) a mental judgment — even a very simple one — we are obviously face to face with a phenomenon belonging to an altogether peculiar order of occurrence. Using the word in the first instance merely for discrimination, we have in the mental phenomenon something at the least as much more complex than a vital phenomenon as this is more complex than a chemical phenomenon. And whether or not there is any scientific advantage (perhaps there is not much) in likening the multiplicity of vital reactions to the reaction of .an automaton, because both are motions determined largely from within, — in the case of mental phenomena, at all events, the comparison is unsatisfactory in every way. While the reference to any internal mechanical arrangement that may be devised gives, on the one hand, hardly the least notion of the marvellous organisation of the nervous system, slowly developed as this has been in and through actual working, it gives, on the other hand, an exaggerated notion -of its independent activity as the organ of what is specially called Mind. For all its apparent spontaneity, the" nervous system as the organ of mind works mainly in response to stimuli supplied by the natural and social environments. Even if nothing had to be said about a subjective repre- sentation of these, to overlook them as factors in the peculiar result which follows from them is to omit all that is most characteristic in the case. But it may be said that it is no part of the doctrine to exclude reference to the external factors : what is really con- tended for is the right to express all the factors, internal or external, in physical terms, or rather the scientific necessity of so doing, and the right to discount all reference to conscious or subjective experience as irrelevant to the scientific issue, whatever other interest it may happen to possess. And truly, though the word Automatism is quite inappropriate as an expression for this conception, it is not for a moment to be denied that the mental life from first to last in all its phases — its potencies, its actuality, its very THE PHYSICAL BASIS OF MIND. 227 aspirations and ideals — admits conceivably of physical ex- pression. But the grave mistake, nay the profound error, is to think of building the science of mind upon such a founda- tion— is to fancy that this way of looking at mind is the only scientific way, or even, in the actual circumstances, at all truly scientific. Would it be right to defer the study of life till physics and chemistry with mathematics are sufficiently developed to furnish a deduction of it, or, if not wholly deferring the study, are inquirers bound to refrain from establishing any facts or laws which they cannot exactly express in terms of chemistry and physics ? Physiologists, by their practice, answer emphatically No, and theoretically they might urge that the chance of ever finding the physico- chemical expression of vital phenomena (to say nothing of their fully reasoned construction) depends not least on the prior ascertainment of the phenomena as vital. With what reason, then, can the impression, or even (as it may be and is) the well-grounded conviction, that mind in all its phases has its physical equivalent, whereby it is brought within the realm of objective nature and may on this side conceivably be studied — with what reason can this conviction be urged against the study of subjective mind, or be made the ground of a serious assertion that consciousness is a mere accident of a certain determinate succession of physical events, when, but as they are subjectively represented, the factors whereon the events depend could not be discerned and brought within the view of scientific inquiry ? A possible assertion it, no doubt, is, and there may even be some use in making it by the way, as a means of lending impressiveness to the affirmation of the never-failing physical aspect of the mental life. But it is no serious assertion to rest in with a view to science, for the reason just given. The conditions natural and social upon which mind and the corresponding series of organic states in point of fact depend, would never come into view at all except in the guise of properly conscious or psychological experience. Only as we are first conscious of influences received from the world of nature and (through speech and otherwise) from our fellow-men, can we after- wards have any true idea of all the (physical) circumstances entering into the causation of that series of nervous positions 228 THE PHYSICAL BASIS OF MIND. which we may come to think of as co-existing with the flow of our subjective life. How then can this be truly described as accidental in the case ? And let it be observed that here the argument is conducted strictly from the point of view of phenomenal science. We may leave out of sight that deeper philosophical consideration, according to which the series of complex physiological events itself appears in ultimate analysis as compacted of a special class of conscious experiences. In my opinion, the Keflex Theory and the more developed Automatic Theory err not in what they really affirm but in what they are understood by many of their advocates to deny. When the Reflex Theory is supposed to mean that the nervous action of the spinal cord is in no way related to the life of subjective experience, it goes beyond the evidence, even although there can be no proof positive of the counter- assertion that every central nervous process is at the same time, in another point of view, a fact of mental experience conforming to psychological law. When the Automatic Theory is given out as meaning that conscious experience has no scientific import, it not only goes beyond the evidence but bars the way against the kind of psychological investiga- tion that practically and theoretically can best be justified. The Reflex Theory brings into view a consideration of great scientific moment when it declares that, without the least reference to conscious or any kind of subjective experience, there is physical provision in the nervous system for the accomplishment of acts most deeply affecting the well-being of the organism. It only errs if it is understood to imply that there is no further question to be asked about such arrangements and that they cannot be at all viewed, either in their origin or in their developed form, as related to the mental life. So also the Automatic Theory advances science when it suggests as a constant problem the expression of all mental phenomena in those objective terms which can be made so much more definite than subjective expression ever is. But it impedes science when it discourages the specific study of mind in all the variety of its actual conditions and manifestations — for the sake of a premature and barren physiological deduction. Will any brooding over physio- THE PHYSICAL BASIS OF MIND. 229 logical data lead to anything but the most vague and general results in the way of psychological inference? Nobody who reflects will pretend that it can ; and one must go further and deny that even the vaguest psychological conclusion can be so obtained, unless with the physiological data there be* coupled unawares some data of purely psychological, which is to say subjective, experience. I would not quarrel with the theory of Automatism on the ground most commonly taken. Though it gives a very inadequate expression to the infinite variety of circumstances determining human actions as viewed objectively, people must learn to be content with the plain truth that man, however he may be " man" (which is saying much), is not "master of his fate," but has his part and lot in the destiny of that — whatever it may be — which is called the physical world. But this truth is little towards all that we want to know of our strange double-sided human existence, and we cannot know more if our scientific activity is to be limited to such abstract theorising as finds expression in the doctrine of Automatism. Mental life can never be understood either in its essence or in its fulness, unless it is studied directly alike as it discloses itself to subjective introspection and as it is manifested more broadly in social relations and in the record of history. The conclusion of the whole matter is that Psychology, however it may be related to biology, must be upheld as a perfectly distinct science — in no sense less distinct than chemistry is from physics, and in truth much more distinct because of the transition from the objective to the subjective point of view. And, returning to Mr. Lewes who has shown himself among the first — who claims indeed in his present preface to have been quite the first — to understand Psycho- logy as the science of Mind in its wider implications, I can- not but venture the opinion that he has not now made all the use that might have been expected of his insight in dealing with the fallacy of " Animal Automatism ". PHILOSOPHY IN EDUCATION.1 A TIMELY question is raised in the foregoing paper,2 and answered with great directness and vigour. The question is opportunely raised at a time when the Civil Service Commis- sioners, whose sway gains with every year upon the higher instruction of the country — as new classes of appointments are thrown open to competition — have decreed that Moral Science shall cease to figure by the side of Logic in the scheme of the long-established Indian examination, giving place to Political Economy. This change was invoked with more than prophetic exactness by Mr. A. J. Balfour in the Fortnightly Review of August last (1877), before the issue of the revised scheme, and its significance is not the less that a year earlier another public body, the University of London, as noted at the time in these pages (No. 4, p. 577),3 was moved in whatever spirit to throw away one of the chief distinctions of its examination-system when it ceased to require of all candidates for the degree of Bachelor of Science some knowledge of Logic and Psychology. Now comes Mr. Stewart's argument, conceived from a quite independent point of view, yet so running in part — where he puts forward Logic but makes conditions about Philosophy — that it might be read almost as a justification of the precise action of the Civil Service Commissioners (or Indian Secretary). Such an apparent consensus of opinion is too remarkable not to require some consideration of its grounds. There may also be some use in confronting with the recommendations of an Oxford lecturer those which a different kind of practical experience would suggest to another teacher. And in a journal that was founded mainly on the faith of the ex- istence of a properly scientific doctrine of mind, it seems right not to pass over some observations that Mr. Stewart makes by the way on the character of Psychology. , iii. 241. 2By Mr. J. A. Stewart on same subject. 3 See above, p. 182. PHILOSOPHY IN EDUCATION. 231 First, a few words on the opinion expressed by Mr. Balfour in the course of a general argument on the Indian examina- tion. In his judgment, Moral Science — meaning Metaphysics and Ethics — fails to satisfy every one of the conditions of a good examination-subject, while Political Economy satisfies them all. The effort of memory, he says, in mastering the subject, should be small compared with the effort of intelli- gence ; it should be easy to distinguish an answer that shows a merely skilful use of the memory from one that shows an intelligent grasp of the subject ; and there should be sub- stantial agreement respecting the body of doctrine in which the examination is held. Waiving the point whether in this last respect Political Economy does at the present day stand in a better position than Moral Science, I should doubt whether his third condition is of as much practical importance for the ends of a selective examination as he deems it, while as to the other conditions it surely might be contended that they are very exceptionally satisfied by Moral Science. There can be no question of "mastering" this subject by effort of memory, nor will an examiner, if he knows his business, have much difficulty in judging whether a student is merely remembering or understands a philo- sophical doctrine. The question, however, that I should like to put to Mr. Balfour is whether it is his opinion that Moral Science should not be studied at all by the class of men whence Indian Civil Servants are drawn. If this is not his meaning, the true way of dealing with the examination should rather be to make it more stringent. What I suppose Mr. Balfour really to mean is that a smattering of philosophical knowledge is not, like some other smatterings, a harmless mental possession ; and this may be freely allowed. It is an evil if hitherto men have been tempted to " get up " a little Moral Science, under the impression that it was an easy way of securing marks. Whether the marks were secured or not, the men are likely enough to have suffered mentally and morally by the venture. But the remedy is to take care, by the nature of the examination if not other- wise, that candidates shall have gone through some real and deliberate study. If it be said that this cannot be provided for, but rather the subject must be dropt out of the examina- 232 PHILOSOPHY IN EDUCATION. tion-scheme as not a "good" one (in the sense of Mr. Balfour's conditions or any other), the effect will be to confirm those people in their opinion who think that the public competitive system attains its end at a ruinous sacri- fice. The mechanical exigencies of the system, thus applied, might easily prove the death of higher academic culture in the country. It may not be desirable that as many youths should take up with Philosophy as with Mathematics- or even Political Economy, but those who follow the philosophic call that comes early to some should not therefore be excluded from the public services.1 Coming now to Mr. Stewart, I find much to agree with in his positions. It is a very senseless or even mischievous proceeding to begin the study of Philosophy with a general view of historical systems ; nor could the reasons against such a course be more forcibly or accurately expressed than by him. It may also be, and doubtless it often happens, that a beginning is made with Psychology in circumstances such that the step is as inappropriate as he describes it. Neither is any fault to be found with his recommendation to begin with a course of Pure Logic : some teachers do this regularly with great advantage to their students, and even boys and girls at school, as Mr. Stewart rightly urges, may thus be led on, almost insensibly, from their grammatical lessons to a first understanding of the philosophical point of view. As little would one think of contesting his view of the general mental discipline that comes of really intimate converse with any of the master-spirits whose thought is of the cast that withstands all change of time. 1 It is only an act of bare justice to acknowledge that the Civil Service Commissioners show the most anxious desire to secure an effective system of examination, and to this intent are never slow to modify their practical regulations in the light of new experience. Nor can it be doubted that the present change in the scheme of examination-subjects — a far more serious matter than a change of working-rules — is meant in the interest of thoroughness. But has it been duly considered in the light of its effect upon the higher instruction of the country? The lowering of the maxi- mum age of candidates for Indian Civil Service appointments, from twenty- one to nineteen, makes an important difference in the case of this particular examination ; still the change, as affecting one of the recognised branches of academic instruction singly, is ominous all the same, and it will press hardly upon students in those parts of the country where Philosophy is studied most and earliest. PHILOSOPHY IN EDUCATION. 233 Is Philosophy, however, only such an T}#Othat the psychology is already philosophy. Let us, first, try to define the true character and position of Psychology, and if we find it to be science of altogether exceptional scope, bringing it into special relation with philosophy, let us next determine the meaning that may be attached to Philosophy in relation to psychology. Psychology, by itself, is, in the first instance, positive PSYCHOLOGY AND PHILOSOPHY. 259 phenomenal science — positive as to its method, phenomenal as to its subject-matter. Its method does not differ from that of other positive sciences, like biology or chemistry, except as the method of any science is modified by the peculiarity of its subject. As phenomenal science, it is occu- pied with a particular class of facts, taken just as they present themselves. Phenomenal facts are appearances (aspects) of things, or occurrences in things as they appear. What is the meaning of ' thing ' or ' appearance ' or ' aspect ' —these are questions which the particular science dealing with any class of facts leaves wholly aside. In so proceeding, the sciences may all be said to begin quite arbitrarily, because the questions are real and remain open ; but the method is justified by the results. It is notorious that all the positive sciences, from mathematics onwards, have become consti- tuted and made way just as they have cut themselves loose from that kind of deeper inquiry. Psychology, too, is science only upon those terms. Not that, in placing it thus far on a level with the other sciences, we commit ourselves to the position that mind is merely such another aspect of things after life (the subject of biology), as life is after material constitution (the subject of chemistry), or material constitu- tion is after motion (the subject of physics). It will pre- sently be argued that there is something in Mind, as the subject-matter of psychology, unlike anything else, that sug- gests the need of some other kind of consideration ; while the fact, evident from the first, that the events or states (or however they are called) which psychology investigates, are apprehended only in the peculiar attitude of introspection, makes already a profound difference. Still there is a definite sense in which we may speak of mental phenomena as of vital, structural or other phenomena ; and in this sense we are entitled, nay bound, from the scientific point of view, to make all necessary assumptions, were it only to get language in which to state our results. The psychologist seeks to assign the natural conditions under which mental experience, as we are each (subjectively) aware of it, arises or comes to pass. For this he as readily assumes ' objects ' (in the sense of material things) as any other man of science, and with as little prejudice to the 260 PSYCHOLOGY AND PHILOSOPHY. deeper question what an ' object ' is or how it can be known. It is plain fact that, but for the presence of what we call external objects in relation with the bodily organism (an- other object, also in its way external), certain of the mental events which the psychologist has to study — those that are called by the general name of Sense — do not come to pass. There is no way of rendering a scientific account of these (that shall be more than a bare subjective description) except in terms of the physical circumstances plainly involved. The circumstances, when more closely examined, are found to consist of physiological processes in an organism, in rela- tion with such physical processes as science discovers upon resolution of the 'objects' of our common or natural expe- rience. Advanced so far as to substitute the exacter expres- sion for the vague opinion of common life that our bodies are somehow implicated with other bodies in the production of conscious experience, the psychologist has then obtained a definite clue for the scientific resolution of the whole complex of mental experience which offers itself to intro- spective observation. Those facts of mental life (subjectively apprehended) are first to be dealt with where there is a clear evidence of physiological process that can be assigned, and afterwards those where the physical conditions are of a more hypothetical character but can- yet be imagined in continuity with those that are more evident ; the same order of treat- ment (from Sense, through Perception and Representative Imagination, to Thought), once it is thus suggested, being confirmed by reference to the historical development of the individual and the race. Nor are the results arrived at less purely psychological because of the regard had to physical conditions. It is not the mere fact of natural concomitance between physical event and mental event that is in this way to be established, though it is of scientific interest and im- portance to ascertain the particulars of such concomitance, as a subsidiary result of the inquiry. The psychologist's reference to physical conditions, so far as it can be carried through, is everywhere made for the elucidation of the facts of subjective consciousness. It is these that he aims at classifying with a view to explanation, and the explanation consists at last in the establishment of laws of mind — laws PSYCHOLOGY AND PHILOSOPHY. 261 which are ' natural,' but still of subjective import. There is thus a perfectly legitimate ' natural science ' of mind (or man), against which, so long as it gives itself out for nothing else, there lies no more objection than against any other positive science. It is a legitimate and also, from any point of view, a necessary task to determine the conditions under which and the manner in which our conscious experience (as iiitrospectively observed) naturally proceeds. The cir- cumstance that the peculiar attitude of introspection must be taken up before the facts to be accounted for are appre- hended, complicates the inquiry with special difficulties but does not alter the methodological conditions under which it may, and (if it will be scientific) must, be pursued. But if psychology is thus, in its way, natural science, it is more also, or rather it leads to more. Mind, however it may be taken as the name for a peculiar class of (subjective) phenomena in relation with other (objective) phenomena, has also a wider implication. The ' other phenomena ' — meaning such 'objects' or objective appearances as physical science investigates out of all relation to the fact of their appearing — have, as the very name ' phenomenon ' implies, their mental aspect. They may be viewed as themselves part of our mental experience : not that this can happen at the moment when they are being taken as the physical con- ditions of the subjective facts which as psychologists we are for the time investigating, but that they can in turn be con- sidered as subjective facts to be investigated. The object (physically understood) which as acting upon the organism gives the only means of stating in scientific terms how we come, naturally, to have such a subjective experience as we call sensation, cannot fail, in the course of the inquiry, to appear as itself also matter for psychological consideration. To be regarded as the condition of our having, in certain circumstances, the particular kind of conscious experience called sense, it must come within conscious ken ; that is to say, it admits of statement in terms of another kind of conscious experience called perception, which has equally to be treated by the psychologist. Or the case may be put otherwise, thus. The psychologist, in giving account of sensation as a rudimentary kind of subjective experience, 262 PSYCHOLOGY AND PHILOSOPHY. has to face the question how sensations appear all, more or less, as objectively referred or projected in an extended order — some appearing so much as sensible qualities of external bodies that it is only by an express eifort that they can be thought of as sensations, others appearing indeed as sensa- tions but thought and spoken of as ' bodily ' from being either localised definitely on the surface of the organism or vaguely referred to some internal part. This is tine psychologi- cal (as opposed to the philosophical or metaphysical) question of Perception, admitting, when so stated, of a strictly scien- tific solution. But what a transformation does such an extension of the psychologist's view not work ! Not a single physical object or fact, as given in common experi- ence or investigated in natural science, or again as assumed for psychological science itself, but now presents itself as a problem to be solved in terms of properly psychological, which is to say, conscious experience. There is, obviously, no science like this Psychology, whose subject-matter, how- ever at first distinguished from that of other sciences, is seen, as we advance, to include (in a manner) the subjects of them all ; which begins with assumptions like the other sciences, but after a time turns round and investigates its own assumptions as no other science does or can. Mathe- matics, physics and all the rest do each their appointed work and have nothing to say to the conditions under which their own or the others' work is appointed. Psychology alone, in doing its work, finds itself occupied (in a manner of its own) with the very matter of the others. Number and space, motion, material constitution, with every other aspect of things that is or can be conceived to be the subject of direct positive investi- gation, are in all their varied modes at the same time facts of conscious experience — in all strictness, mental phenomena, of whose elements and composition account may be rendered from the psychological point of view. If such account may be given, how can Psychology be spoken of as if it were only one among the other sciences, touching the philosopher, who comprehends things universally, no more nearly than any other? Psychology is not philosophy, but with Mind for its subject its scope cannot be less wide than the scope of philosophy. That is not to be said of any other science. PSYCHOLOGY AND PHILOSOPHY. 263 It is no wonder, indeed, that psychologists have slipped into philosophical consideration as other men of science have not, or that those philosophers who set store by scien- tific psychology have not been too careful to distinguish and separate the one kind of consideration from the other. If philosophy is, on the theoretic side, the comprehension of things as known, and, on the practical side, the valuation of things as ends to be striven for, what more natural than that the scientific investigation of the various phases of our complex mental life — distinguished, so far as they can be distinguished, under such heads as knowing, feeling and willing — should be mixed up with or have mixed up with it the philosophic inquiry? The conjunction is much to be deprecated, when we see how it gives occasion for groundless objections against the method of psychology as science. It is equally to be deprecated, if it can be shown to impede the free exercise of philosophical thought. But the fact that psychology and philosophy so readily intertwine is surely an indication of some special affinity between them. Let us now take up the question of their relation from the side of Philosophy. We have seen psychology refuse, because of its subject, to be classed as merely one science among the others. How shall we understand Philosophy in relation to the sciences generally, and more especially in relation to that science of psychology whose scope widens out into an all-comprehensiveness vying with that of philosophy itself? Locke, who first, in whatever inarticulate fashion, pro- claimed the necessity of starting with psychology, had a clear notion of the function of Philosophy in general, which his followers have too much lost sight of, some in their efforts to improve his psychological ground-work, others in their predominant concern to work out special theories of ethics or of logic from psychological data. If we discount Hume's Treatise of Human Nature because of its equivocal import, there has not been since Locke's Essay any work of comparable range in general philosophy produced by an English thinker from the psychological point of view. Be- yond psychology, English thinkers have occupied themselves mainly with Ethics, till Mill in his Logic essayed the special philosophical task of providing a theory of scientific proof; '264 PSYCHOLOGY AND PHILOSOPHY. or if the present day has witnessed more than one notable achievement in general philosophical construction, these have not been projected directly, if at all, upon Lockian lines. Locke's notion of philosophy is of a general Theory of Knowledge wrought out, with psychological data, as com- plementary to the positive sciences. While this or that science is concerned with a particular department of experi- ence or aspect of things as we find them, it is the business of philosophy to investigate the possible range of experience, to distinguish between what can and what cannot be known, and in particular to determine the conditions and content of real knowledge- -all upon foregone psychological inquiry of the positive sort. Now this is the view of philosophy (on its theoretic or speculative side) that will force itself most directly upon any one who, being interested in mind as a subject of science among other subjects of science, cannot help seeing that mind has also a deeper implication which no positive science can resolve. Apart from any question of psychology, it is notorious that (speculative) philosophy has in modern times changed its character from a theory of Being into a theory of Knowing. This has been mainly due to the rise and development of the positive sciences, as appears not less clearly in Kant's than in Locke's statement of the philosophical problem. The sciences are there as so many bodies of coherent doc- trine about this or that kind of fact. The more special of them presuppose and are advanced by help of the more general, but, as has been already remarked in another con- nexion, not one of them (always excepting psychology) has any light to throw upon the matter or assumptions of the others. They employ a language which none of them (unless, again, psychology) is in any way able to explain : 'object,' 'thing,' 'substance,' 'quality,' 'aspect,' 'pheno- menon,' ' relation,' ' cause,' &c., &c. — how can any of the sciences proceed without the use of such words as these, but which of the sciences has any account to give of them ? Clearly, then, there is just as much need of a theory of the conditions of knowing anything as there is of a theory of this or that kind of thing. The theory of this or that kind of thing (as found) is what we call a science. The further PSYCHOLOGY AND PHILOSOPHY. 265 indispensable theory of what the meaning of science or any kind of knowledge is, may or must be called Philosophy. So far all are agreed who will think of philosophy in relation to science ; and not only (though more) in modern times, for,, with a less definite conception of special science, Aristotle ;also had his view of ' First Philosophy ' as general theory of knowledge. Consider now the science of psychology in particular. Psychology also, as dealing with a special kind of fact, needs to be supplemented (as science) by philosophical consideration. But psychological fact includes the very function of knowing, which is the subject of philosophy. A different statement of the relation of philosophy to psycho- logy is, then, required than in the case of other science. There it was enough to say that philosophy has the task of analysing to the bottom the conceptions and assumptions which the sciences generally or any sciences in particular employ without being able to give account of them ; being thus fundamental theory of science while science is theory of things as they appear. Here, where the particular science (psychology) and philosophy have both to do with the fact or function of knowing, the statement must be that they have a different kind of account to give of it. And there is room for such difference. When psychology has ex- plained knowledge as a phase of conscious experience natur- ally conditioned, there remains for philosophy the question of its import or validity as knowledge. The distinction may, first, be made plain by an example. As we have already had occasion to note, the psychologist is met at the earliest stage of his inquiry, when treating of sense, by the remarkable fact that sensations, which he must regard by themselves, analytically, as purely subjective states of feeling (arising in physical and physiological cir- cumstances that can be assigned), do yet appear in actual experience with varying characters — some vaguely and others definitely referred to parts of the physical organism, while still others are projected so as to appear naturally as qualities of external things. We need not pause now to state the case in all its variety more exactly : it is met by the psycho- logical distinction of perception (sense-perception) from sen- sation, perception being a cognitive or intellectual process PSYCHOLOGY AND PHILOSOPHY. resulting in what are best called percepts. A percept is a particular fact of intellectual experience, as singled out for investigation — when it can be proved to be essentially com- plex, however apparently simple. Now in any such percept, as, for example, a definitely limited portion of space, or a particular object in space with a variety of sensible qualities, the psychologist's interest ends when he has shown' what elements (not further analysable) of sense it involves and under what laws these come to be so ordered or fused as they appear in natural experience. The psychologist's in- terest ends and just then the philosopher's interest begins. Both agree in regarding the portion of space or sensible object as percept, that is to say, as fact of conscious experi- ence, not (as in physical investigation or common life) as fact or thing out of relation to mind. But while the psy- chologist has in view the percept only as it is perceived and explains howr the perceiving comes to pass (in me or in you), the philosopher asks what the perceiving imports (for you and me equally) — in particular whether it means or need mean, as it is commonly taken to mean, a thing independent of the perception of either of us. What is the space or object that we perceive ? What more is there in it as per- ceived, than as fancied ? If said to be real or objectively valid (as a subjective fancy is not), what makes it so? These and the like questions, which it is not for the psychologist to answer (though it were allowed that he can best put them in train for answer), touch the very heart of what we mean by Knowledge. We may view knowledge as mere subjective function, but it has its full meaning only as it is taken to represent what we may call objective fact, or is such as is named (in different circumstances) real, valid, true. As mere subjective function, which it is to the psychologist, it is best spoken of by an unambiguous name, and for this there seems none better than Intellection. We may then nay that psychology is occupied with the natural function of Intellection, seeking to discover its laws and distinguishing its various modes (perception, representative imagination, conception, &c.) according to the various circumstances in which the laws are found at work. Philosophy, on the other hand, is theory of Knowledge (as that which is known). PSYCHOLOGY AND PHILOSOPHY. >2(i7 But, if we thus take philosophy as Theory of Knowledge, beyond psychology, it needs to be denned on other sides also :' in relation to Logic, accepted as this has been for philosophical doctrine by none more expressly than by Mill and others among the later representatives of the psycho- logical school ; and, again, in relation to Metaphysic, the most widely accepted synonym for anything that can be called Philosophy. What we may leave aside, on the pre- sent occasion, is the question what other definite lines of philosophical thought are opened up for the psychologist by the other phases of mental life which he distinguishes, from Intellection, as Feeling and Will. It, of course, follows that there are such other lines, when it is seen how the psycho- logy of Intellection passes into philosophical Theory of Knowledge ; but the present object is not to lay out the whole philosophical field — only to indicate a point of view. There is special need of distinction between Logic and Theory of Knowledge; for some (as Hegel) would use the very name Logic for philosophy when conceived as Theory of Knowledge, and others fas Mill), while retaining the traditional conception of Logic, though widening it in a cer- tain admissible way, are found importing into the exposition (as in Mill's^chapter iii., "Of Things denoted by Names'") a series of considerations which are plainly extra-logical and can only be called epistemological. And, from any point of view, is not Logic a philosophical theory of knowledge? What is valid knowledge '? When is knowledge valid so as to command universal assent ? What is known truly and what not truly ? These questions, which we have used to express the problem of philosophy as opposed to psychology, seem to apply equally to the problem of Logic. Logic is un- doubtedly concerned with validity of knowledge. But know- ledge to the logician is what is more particularly called Thought ; some saying this expressly, others meaning Thought generally when they adopt the more special name of Reasoning, and others implying the same thing when they speak of logic as having to do with validity of Inference (formal and material) or the conditions of general Proof. Now if we substitute the word Thought, which properly means general intellection or intellection by way of concepts, PSYCHOLOGY AND PHILOSOPHY. for the word Knowledge in the questions just repeated, to make them more accurately express the subject-matter of Logic, we get at once a clue to its distinctive feature an compared with Theory of Knowledge. Logic, while equally with Theory of Knowledge to be dis- tinguished from psychology as occupied with the philo- sophical question of validity, is to be distinguished from Theory of Knowledge in having to do with the validity of Thought only as it is general. This view of Logic, as having for its subject the import of the generality of general know- ledge, agrees either with the limited conception of the doctrine as Pure or Formal Logic or with its range as widened to include Applied or Material Logic. Even when applied to this or that particular kind of matter, Logic goes no further than to determine the conditions of valid general statement (as deductively or inductively obtained) in the particular kind of matter. It does not probe the deeper questions remaining for Theory of Knowledge in regard to any matter of thought. It belongs, for example, to Material Logic to explain the form, mainly deductive, that geomet- rical reasoning assumes and to determine the conditions of the valid proof of general statements in geometry ; but what space may in the last analysis be, whether it is a subjective form of our sense-perception or has any kind of extra- mental reality — these are questions which do not concern the logician except in so far as the answer given to them in ultimate philosophical analysis can be shown to affect the question of the form of general statements in geometrical science. This it very well may or indeed inevitably must do : the present contention by no means is that Logic is not related to Theory of Knowledge. Not only, in the view here suggested, may Logic be regarded and treated as a special department of the general philosophical theory, but, even when constituted into a separate doctrine (sometimes called a special science, though it is no science as mathematics and the rest are), it may constantly have to reckon with episte- mological considerations — as the practice of all logicians shows who (like Mill) do not confine themselves to the mere form of thought. All the same, it is not to be confounded with Theory of Knowledge. It deals so exclusively with PSYCHOLOGY AND PHILOSOPHY. '269 the one aspect (generality) of such knowledge as it deals with at all that, unless it be denied that this should or can be investigated apart, the line of demarcation is clear ; and as it has not been doubted, from the time of Aristotle, that the aspect is one that can be treated apart, so neither will anybody doubt that it should be so treated who is interested in making knowledge scientific and is alive to the fact that it is of the essence of Science to be general. If philosophy as Theory of Knowledge is thus perfectly consistent with or even includes the traditional conception of logic as a department of philosophical doctrine, we may next see that it consists as well with the conception of philo- sophy as Metaphysic, though taken in no sense short of that which is otherwise expressed as Ontology or Theory of Being. This sense of the word Metaphysic, historically best justified, is also that which is suggested by analogy with the meaning of Physic. Physic (in its widest application) is concerned about the being of things as they appear — about things only as they appear but yet as they appear to be. Metaphysic, as going beyond Physic, has then to do with the being of things as they are or with their being as the ground of their appearing. But how can such a notion of philosophy as ontological doctrine be entertained at this time of day ? It is not only English psychologists, content with their ' mental phenomena/ that have abjured ontolo- gical consideration. When Kant substituted criticism of pure reason for dogmatic assertions about a sphere of super- sensible existence, did he not establish for evermore that not Being but Knowledge was the proper subject of philosophy? The critical inquiry which he thus put foremost did not, however, preclude Kant from following it up with a ' Meta- physic ' (of Nature as well as of Morals) as the proper fulfil- ment of philosophy ; and nothing hinders the philosophic thinker who begins by defining his task (in relation to psychology) as Theory of Knowledge, from considering it as Theory of Being (Ontology) also. The one, indeed, is in- evitably the other. The thing that is known, is known to be. The thing that is, is not otherwise than it is known. What it is important to understand — what has come in the progress of modern philosophy to be clearly understood — is, '270 PSYCHOLOGY AND PHILOSOPHY. that no dogmatic assertion of Being is philosophically admis- sible. Before it can be determined what in any ultimate sense is, what the modes of Being are, it must first be deter- mined what the modes of Knowing are, what in the ultimate sense is known. This is the idea common to the Critical and to the Psychological school of philosophy. But that is no philosophy which, after considering, by one method or another, what it is to know anything and what is or can be known, starts back from declaring what then must be understood really to be. Philosophy has not only to give the ultimate analysis of things in abstract terms (of subje'c- tive import), but must render account of the concrete realities of everyday experience, which in the truest sense are for us all because it is to them (animate or inanimate) that all human interest attaches — because it is they only that are conceived as having an intrinsic or extrinsic worth. The philosophy that attempts this is metaphysical in facing a, problem that can be expressed in no terms of physical science. It is ontological in seeking to appreciate the ulti- mate meaning of whatever can be said to be. It seems, then, that there is nothing within the possible range of philosophy that need remain sealed for the thinker who starts from the psychological base more than for any other. In point of fact, the ' English ' thinkers, when in the properly philosophic vein, have no more than others been slow to declare how they conceive of things as, in the last resort, being. They are only chargeable with having allowed themselves to be led, by their method of approach- ing philosophical questions, into an unsystematic and dis- jointed treatment of them. The advantage to be obtained by a clear distinction of Philosophy from Psychology would tell in favour of both, but especially of Philosophy which thus far has had its development most hampered in a conjunction which has not seldom been a confusion. There is nothing to hinder the thinker who works up to philosophy by way of psychology from grappling with the general problem of Knowledge, in as thorough a spirit of system as has marked any of those, from Kant onwards, who have thought it the -chief merit of their philosophy that it has been wrought out •on a plane immeasurably higher or deeper than the level #t PSYCHOLOGY AND PHILOSOPHY. '271 which psychologists creep along. There is nothing to hinder, and his very psychology should rather urge him on to the work of systematic interpretation, for which it sup- plies the means as well as the motive. At least it is plain that no psychological thinker need philosophise less syste- matically than Kant, whose whole scheme of critical inquiry has its stages psychologically determined. .But, after all, the question is not whether psychologists can become philosophers — as, of course, they can if they will, or even whether psychologists are inevitably deter- mined, as other scientific inquirers are not, to pass from conclusions of science to the probing of human knowledge to its foundations. The real question is whether the philo- sopher in this (or other) part of his task is specially helped by foregone psychological consideration ; and this has not yet been directly met. The previous remarks, however, would seem to warrant an affirmative answer. If it can be shown (as here it has been suggested) that there is 110 problem of philosophy which the psychologist does not have specially forced on his attention at one or other stage of his science, while his science gives him the means of considering it with a definiteness of insight and in a methodical spirit which interest in the deeper meaning and issues of things does nothing of itself to guarantee, then it cannot be otherwise than helpful to come to the work of philosophy from the side of psychology. Though philosophical questions are not to be solved under the same conditions of strict verification as are possible in phenomenal science, philosophers as well as scientific men desire to gain universal assent for the solu- tions they propound. Philosophy, however differing from science in its subject-matter, yet aims at the form of science. It has been advanced most permanently, in all ages, by those thinkers who were familiar with the best information their time afforded in the way of special science. If, then, it appears that there is one science which, while it is related to the other sciences in method, has so far common subject with philosophy that it is with Mind they are both (in what- ever different way) concerned, the methodological advantage of working into philosophy through the science of psychology is hardly to be denied — even though the practical proof may- 27'2 PSYCHOLOGY AND PHILOSOPHY. yet remain to be given by psychologists that they can be as thorough and comprehensive as they have hitherto been sober and cautious in their philosophic thinking. Meanwhile it may be observed how psychological science, working within its own limits, has obtained results whose philosophical import is in surprising agreement with con- clusions which it is thought the greatest triumph of a very different method to have been able to establish. Any regret, indeed, that may be felt at the isolation in which English thinkers have held themselves from the Kantian movement in philosophy — being content to work on from their psy- chological base as if it had never been questioned — is tempered when it is seen what independent progress they have been able to make upon their own line towards a common goal. That is no argument for maintaining the isolation, but may be held to prove that the method of psychological approach is not philosophically valueless, and gives ground for the belief that it has only to be more systematically followed out for the achievement of as great results as have ever been claimed for another way, while in this way the results are more likely to secure general ac- ceptance. Let us, in concluding these remarks for the present, note but two points in the philosophical theory of knowledge which, since the time of Kant, may be regarded as placed beyond reasonable question : (1) that we know Space, abstractly, as a ' form ' inclusive of sensation and, actually, as one great continuum (percept, not concept) within which all sensible objects are ordered ; (2) that anything to be definitely called Object, as a sensible reality for all men alike, is a complex product of thought-activity working under common conditions in all. Now nothing is more remarkable than the different accounts which the earlier and the later English psychologists give of the perception^ of space and of 'external objects'. Compare with Locke's crude notion of space, as a direct and simple datum of touch or .sight, the present psychological theory that we acquire perceptive consciousness of it by active synthesis, through muscular organs, of elements of (passive) sensation ; or, again, compare with even Hume's insight (so greatly marked beyond anything in Locke or Berkeley) into the PSYCHOLOGY AND PHILOSOPHY. 278 processes of intellectual elaboration involved in objective perception, the grasp that psychologists now have of the representative factors that more than any presentative elements explain how the percept appears as it does. I do not say, here more than before, that the psychological are the philosophical questions, but I say that there is no aspect of the philosophical questions which may not be better understood and more definitely treated because of the psychological insight that has been gained. There is nothing in Kant's philosophical analysis of either fact of cognition — nothing, that is to say, which from the point of view he places himself at may be unquestionably maintained — for which a positive psychological warrant cannot now be assigned ; while it is psychology that gives the clearest demonstration of the limits that should be placed upon his assertions (especially as to the universality of the space- form as regards 'external' sense). If that be so, Psycho- logy is amply avenged upon him for his despite. 18 LEIBNIZ AND HOBBES.1 THE recent discovery in the University Library at Halle of a large number of letters from the unwearied hand of Leibniz — surely the most epistolary of all great thinkers — does not thus far prove to have much philosophical importance.- Dr. L. Stein, editor of the new Archiv filr Gesch. der Phil., has in the first two numbers of that review given a careful account of all the autographic letters found, to the number of 101 ; and the utmost that can be said of them is that they help to deepen, if that were necessary, the impression of Leibniz as a man to whose breadth and variety of intellectual interests there was no bound, but who yet could pursue with the utmost tenacity special scientific objects of his own, — as here the perfecting of his reckoning-machine, entrusted, from about 1700 (long after its first invention), to a Helmstadt mathe- matical professor, R. C. Wagner, his chief correspondent in the collection. There is promise, indeed, that in the next number of the Archiv some other of the Halle letters — but these only copies, though not before published — will be made to yield matter of philosophical interest, as touching the question of the scope and value of history of philosophy. Meanwhile it may be noted that the discovery at Halle is not the only addition that has just been made to our knowledge of Leibniz's amazing activity as a letter- writer. There has recently appeared vol. iii. of the division given to ' Corre- spondence ' in the stately collection of Die philosophischen Schriftcn von G. W. Leibniz (Berlin, Weidmann), made since 1875 by C. J. Gerhardt, editor before of L.'s Matheinatische Schriften. This volume was kept back while vols. iv.-vi. of ' Works ' were being issued from 1880. Apparently, though the editor says nothing, some kind of supplement must still be in view, outside of the original scheme ; various things remaining unaccounted for within either division, as, for 1 Mind, xiii. 312. LEIBNIZ AND HOBBES. 275 Example, the well-known correspondence with Samuel Clarke. With all his merits and his unique claims to the gratitude of Leibniz-students, Gerhardt, it must be said, has not in all respects chosen the happiest way of presenting the fruits of his research ; in particular, he might have been more forward with the reasons for some of his action in the past, and now he might have been less silent as to his actual intentions. There can, however, be no question as to the philosophical interest and value of the new, and hardly less of the corrected, matter which, in all his volumes (of ' Works ' as well as ' Correspondence '), he has, with extraordinary labour, been able to bring forth from the recesses of the Eoyal Library at Hanover. In his latest volume — to go no farther back — at least one important interchange of letters (with Jacquelot, pp. 442-82) is made known for the first time ; while other correspondences, more or less imperfectly printed before (some in merest fragment), are now set out with all desirable fulness and care. Among these are three : (1) with Thomas Burnett of Kemnay, a Scottish friend of Locke's ; (2) with Cudworth's daughter, Lady Masham, the comforter of Locke's declining years ; (3) with Pierre Coste, the French translator (in England) of Locke's Essay, — which throw so much new light on the relations of the German to the English philo- sopher that another occasion may be sought for giving some detailed account of them in these pages. At present there is something to tell, from another source, of the relation in which Leibniz stood to an earlier English thinker — a relation that had not before been half carefully enough studied, and which, indeed, has been wholly overlooked by most expositors of Leibniz, including Mr. Theodore Merz, who, in his excellent contribution to " Blackwood's Philosophical Classics " (see Mind, ix. 439), first set the great German fairly before English readers. It is that earnest student of Hobbes, Dr. Ferdinand Tonnies, who, in a recent article in the Philosophische Monatshcfte (xxiii. 557-73), has placed in a light as striking as it is new the intellectual debt of Le bniz to Hobbes. Leibniz, it may be well to remind the reader, was contem- porary with Hobbes in the last third (1(546-79) of the nonagenarian's life. It has long been known that the ardent 276 LEIBNIZ AND HOBBES. young thinker, impressed at an early age by Hobbes among other of the new ' mechanical ' philosophers, sought to enter into closer relations with him by a complimentary and interrogatory letter, written from Mainz in the year 1670. The letter was first printed, from a copy of it taken by Oldenburg through whom it was sent to Hobbes, in Guhrauer's biography of Leibniz, whence it passed without change into Gerhardt's vol. i. pp. 82-5 (having, by the way, its gist some- what too loosely represented at p. 48). Now Dr. Tonnies has had the good fortune to find, in the same volume (4294) of SI. MSS. in the British Museum with Oldenburg's copy (nearly correct in itself, but not always carefully followed by Guhrauer), a document that has all the appearance of being Leibniz's original letter. Of this he gives the first quite accurate transcript, appending to it a series of remarkably instructive " elucidations ". For the understanding of the development of Leibniz's thought — a subject of peculiar interest and difficulty — Dr. Tonnies's few pages make more really effective use than has yet been made of the rich material now rendered accessible by Gerhardt's diligence. It has recently been used, not without effect, by Dr. David Selver for two elaborate articles in the Philosophische Studien (iii. 217-63, 420-51, "Der Entwickelungsgang der Liebniz'schen Monadenlehre bis 1695 ") ; but this careful writer, who ranges also over a wider field to good purpose, has overlooked, like others before him, the facts now discerned, with characteristic penetration, by Dr. Tonnies. When read in connexion with the various utterances in letters or other writings from 1663 which Dr. Tonnies has been the first to marshal, the letter of 1670 leaves it hardly doubtful that, up to this date at least, Leibniz was more deeply affected by Hobbes than by any other of the leading spirits of the new time. If as late as 1669 he could, in a letter to J. Thomasius, express a preference for the doctrine of Aristotle's Physica over that of Descartes' Meditationes, he cannot have been very familiar with this treatise, so purely philosophical in character as it is, and it may well be doubted, with Dr. Tonnies, whether he can by that time have read at all Descartes' chief work, the Principia Philosophies, which does contain a physical, as well as meta- LEIBNIZ AND HOBBES. 277 physical, doctrine. To be sure, the letter of 1670 itself includes a very high-flown reference to the French philoso- pher, but there is every reason, notwithstanding, to believe that Leibniz's serious occupation with Descartes' philosophy followed upon the years from 1672 in which he gave himself with such ardour and brilliant success to the study of mathe- matics ; as, probably, it then was from the sense of having so swiftly surpassed Descartes in mathematical discovery that he always continued more eager to accentuate their differences than their agreements in philosophy. On the other hand, we find him, by the year 1670, riot only conversant with Hobbes's thought at all its stages, whether of principle or application, but evidently concerned to get some accommo- dation of it to those practical interests of religion which were uppermost with him all through life. The time was near when he could not retain the faith he may have had even in the mathematical pretensions of the De Corpore, but, as Dr. Tonnies shows, other ideas, logical, metaphysical and even physical, plainly to be traced to that work, remained always operant with him. The most signal, undoubtedly, is that reference by Hobbes, in De Corpore (c. 25, § 5), to the possibility of regarding all bodies whatever as endued with sense in so far forth as reactive, though he himself proceeds to urge that it should be limited to living creatures, which do not simply react but have special organs for the retaining of impressed motion or — as he interprets this — have memory. Leibniz clearly has the passage in view when, in the letter of 1670, he goes so far beyond Hobbes (in the direction of Descartes) as to doubt whether sense can be more properly ascribed to brutes than "pain to boiling water". But already in the following year, as Dr. Tonnies points out, he is found harking back, in the tract Theoria Motus Abstracti, to a position which is essentially the same as Hobbes's, though he gives it an affirmative expression, peculiar to himself, which is of the utmost significance in view of the Monadism of later years. Two sentences may here be quoted : " Nullus conatus sine motu durat ultra momentum, praeterquam in mentibus. . . . Omne enim corpus est mens momentanea, sed carens recordatione." It did not escape Leibniz's con- temporaries whence he had got his inspiration ; for Dr. '278 LEIBNIZ AND HOBBES. Tonnies is able to cite the words of mournful reproach with which a forgotten G. Kaphson, in controversy with Leibniz on the point, brings forward the very passage from Hobbes. Dr. Tonnies himself, in view of it, and in view of the further development of Leibniz's thought that may now be referred definitely to 1678 (since publication by Gerhardt of his marginal notes written on Spinoza's Ethica in that year), does not hesitate to describe his metaphysical doctrine as, in strictness, " a Hobbism that had taken up Spinozism into it," or, again, to say: for Leibniz "Hobbism is the true physics; Spinozism, the true psychology". However this may be, — and certainly account has to be taken of a number of still later stages of development, at least in expression, before Leibniz, close upon the end of the century, had final possession of his doctrine, — enough should have been said to show that Dr. Tonnies has done a real service in drawing attention to an aspect of it that in recent times has not been at all regarded. The letter to Hobbes (then eighty-two) remained un- answered for all its compliments, which should not have been ungrateful to the old man amid so much hostile clamour as attended his closing years. Dr. Tonnies is doubtless right in ascribing to disappointment the petulant terms in which Leib- niz, writing to Thomasius some months later in the same year, speaks, on Oldenburg's authority, of Hobbes as passing into second childhood. It must have been a transient shade of feel- ing, for some time later — apparently in 1672, from Paris — he began to address another letter of appreciative criticism to the aged thinker (given by Guhrauer and Gerhardt from the unfinished draft at Hanover). There is no evidence of their having met when Leibniz came over for some weeks to London, early in 1673 ; most probably, Hobbes was then in Derbyshire. THE PSYCHOLOGICAL THEORY OF EXTENSION.1 THE effort so often renewed since the days of Herbart to construct a psychological theory of Extension has so far had results that appear to be hardly more satisfactory to those who may be supposed to maintain than to those who dis- count the enterprise in principle. Some recent treatment of the subject by writers whose scientific earnestness is "above question makes it worth while inquiring what may be the reason of the discontent or disagreement in regard to it so patent among psychologists. For this purpose I will here assume, without argument against those of the other way of thinking, that there is nothing in our perception of Ex- tension to set it beyond psychological analysis. It is one thing, indeed, to seek to determine (psychologically) how we come by the perception, and quite another to determine (philosophically) what import is to be ascribed to the ex- tension of body or to the space it appears to fill ; but, this borne in mind, there is surely no more legitimate, or even imperative, task than to attempt to explain how body comes to appear as spread out in what we call space. Now why has this question failed to get a solution commanding some- thing like general assent ? I would suggest that it is chiefly because of the way in which it is too often taken up. It should be taken up, as I will try briefly to show, after and not before, or at least in definite and express relation to, a certain other question. The point has not been overlooked by some — for example, Prof. Bain and still earlier writers —but it has not been urged with all the persistence or con- sistency that the case seems to require ; nor has it yet (that I know of) been urged at all in relation to the later manner of stating the problem that has come into vogue under German influence. 1 Mind, xiii. 418. THE PSYCHOLOGICAL THEORY OF EXTENSION. Among recent work on the space-question from the psychological point of view, I refer, of course, chiefly to Mr. Ward's now celebrated article in vol. xx. of the Encydo- pcedia Britannica, and to the remarkable series of dissertations by Prof. James that ran through last year's Mind (1887). The work of these two writers may first be noted for the confession it seems to involve of something very like psycho- logical impotence.1 They have been, independently, driven to make assumption of an inherent character in sensation that brings them perilously near, if it does not quite carry them over, to the position of those who contend that a psychological theory must always include among the ele- ments of the explanation, though it may be under some disguise or other, the very fact of extension to be explained. With Prof. James, indeed, there is no disguise and it is difficult to see in what respect he does not go over. All the pity that his historical epilogue showers upon Kantians that know themselves and (more liberally still) upon Kan- tians that know themselves not, does not alter the essential import of his own round declaration of a primitive experience of "bigness or extensiveness " in all sensation. Within their general assumption as to the nature of space, the followers of Kant have found it no less possible or necessary than Prof. James to inquire what are the precise factors of sense and intellect entering into our various perceptions of extension ; and for the start it really matters very little, in the psychological point of view, whether space is called ' pure form ' with (external) sensation for ' matter,' 'or whether we are told, as by Prof. James, that "extensiveness'' 1 Compare Mr. F. H. Bradley's incidental remark in Mind, xii. 869 n. : " All the attempts which I have seen made to derive extension from what is quite non-extended in my opinion break down ". Mr. Ward had expressed himself to similar effect thus (E. B., xx. 53 b) : " The most elaborate attempt to get extensity [ ? extension] out of succession and coexistence is that of Mr. Herbert Spencer. He has done perhaps all that can be done, and only to make it the more plain that the entire procedure is a vtrrtpov Trporepov." Whether Mr. Ward's own derivation of extension from or with help of ' extensity ' is more satisfactory to Mr. Bradley does not appear. At all events, it is not covered by his remark ; for the extensity claimed (as well as intensity) for sensation cannot be understood as " quite non-extended," if it is to do the work of explana- tion which, without it, Mr. Ward considers so hopeless. As to vvrtpttv irpdrtpov, on one or other side in the case, something is to be said above. THE PSYCHOLOGICAL THEORY OF EXTENSION. '2H1 is an empirical aspect of sensation, justifying the use of such terms as " sense-space," " spatial feeling," and even " sensa- tion of line or angle " ! This novel kind of psychological speech, if fit to raise the hair of other people besides Kan- tians, does yet not keep himself from saying, with any Kantian of them all, " that, within the range of every sense, experience takes ab iuitio the spatial form " (p. 30). " Ab initio ! " — there lies, in regard to the fact of " spatial form," the question for the psychologist as it has come to the front in this century, not least by reason of Kant's (philosophical) analysis carried so much deeper than any- thing attempted before. Let it, however, be observed in passing that, even for the psychologist, the question is not so much of beginning of the individual's mental life — in respect of which the truth may lie one way or the other according as the evidence, if only it could be forthcoming in any decisive shape, may determine — as of beginning of scientific consideration.1 Is the spatial form, in which at least some (we need not now ask whether all) sensations are experienced, so inextricably present with them from the first and always, that it cannot be viewed apart and reason- ably shown to have a derivation from certain mental data presumably simpler? Now the allowance may at once be made that data of the kind usually assigned, at least in the way they are assigned or usually employed, fail to afford a satisfactory explanation. The data are ' muscular sensa- tions,' in relation always with elements of (passive) touch and sight, and certain laws of intellectual grouping under which the sense-elements are supposed to be worked up. When the data of the so-called muscular sense are repre- sented as ' feelings of movement,' the work of explanation is not, indeed, found difficult ; but then, as has rightly been objected, the whole question is begged, since ' movement ' plainly presupposes 'space'. If ' muscular sense ' is under- lfThis is said not without reference to the argument conducted by Dr. E. Montgomery in his important series of articles on " Space and Touch " in Mind, vol. x. Dr. Montgomery's earlier contention, in the work on Kant with which he first came before the philosophical world (Die Kantische Erkenntnisslehre widerleyt vom Standpunkte der Empiric, Miinchen, 1871), seems to me to have lost nothing of its essential psychological value. '282 THE PSYCHOLOGICAL THEORY OF EXTENSION. stood in its purity as ' sense of effort,' we have, by the side of tactile and ocular sensation, merely another, though it may be a quite peculiar kind of intensive element ; and the difficulty is then serious enough, how a variety of intensive elements can come, by any means of grouping, to assume in consciousness the appearance of an extended order. Through repetition, reversal, &c., elements apprehended at first in succession may very well end by appearing as co- existent, but it is still a far cry from coexistence-in-time to coexistence-also-in-space, which is the meaning of extension. How is the transformation to be effected ? Or, rather, can it any way be effected ? I do not know that it can, if sought for upon that line. But perhaps there may be no such diffi- culty, if it should appear that the problem of Extension is one not to be thus directly faced. Doubtless, Extension is the fundamental aspect of the objective world as it offers itself to our apprehension. In our everyday view of things, which psychology has to render account of, space has the same appearance of external reality as the body that fills it ; and extension is the one attribute that is common alike to bod}7 and to space. It must be a consideration of this kind that induces even Prof. Bain, with whom extension later on takes a secondary place, to begin his whole psychological doctrine with a distinction of "object "and " subject " as the Extended and Unextended — a distinction which Descartes and others are there to support with the metaphysical assertion that extension is the one essential attribute of whatever is other than mind. However it be with the metaphysical fact, which does not now concern us, certainly we must grant to the full the universality of the problem of Extension as it offers itself to the psychologist in regard to the world of sensible experience. It does not, therefore, follow that the problem is the first to be attacked in working out a theory of objective perception. Extension is the fundamental aspect of sensible object only in a logical point of view. There is every reason for assert- ing that it is not the historical prius in our actual apprehen- sion of object. Will any one, upon reflexion, maintain that a child becomes aware of Space, which is extended and only extended, before it is aware of Body, which is resisting as THE PSYCHOLOGICAL THEORY OF EXTENSION. 283 well as extended ? It cannot seriously be doubted that we arrive at our perception of space by a literal evacuation of, and thus after, the fuller and more impressive perception of body. Now, if this be so, we surely have here the right clue to the order in which psychological explanation should be attempted. The difficulty of the problem in the form now commonly given to it lies, we have seen, in getting elements of ex- perience, all in the first instance describable as ' intensive ' only, to acquire the ' extensive ' character. Intensive ex- periences continue always to be referred to the subjective mental stream flowing on in time. On the other hand, experiences of the extended order — without ceasing to be interpretable as experiences (else they would not concern the psychologist) — have the appearance of being detached from the mental stream; and- are then called 'objective'. Now so long as no suggestion of a reason is afforded why they should thus become detached, the difficulty remains un- solved. Within the mental stream intensive elements may, in the way before mentioned, become aggregated into what appear clusters of concurring events, but upon that line nothing more seems possible. Let them, however, in the form of such time-clusters, be experienced in connexion with something that is already construed as external object, and at once they may begin to take on a new char- acter by reference to this. I have said ' external object \ for the sake of definiteiiess, not because I am not well aware that the word '.external ' — understood with reference to the bodily organism of the perceiver or in any other way — may be said, here again, to beg the whole question at issue. Upon the ' externality,' as such, no stress can rightly be laid at the outset. It is ' object ' (in whatever vague or shadowy sense of a not-self) from which the start has to be made ; and ' object ' — as indeed the name implies — is just ' obstacle,' without at first implying anything more. All psychologists may be said now to be agreed upon this, that it is in the phase of resisted muscular activity that we first become conscious of a 'not-self as opposed to 'self: not that we all at once achieve the distinction, but that we gradually attain it through experience of this kind. Analyse the '284 THE PSYCHOLOGICAL THEORY OF EXTENSION. experience, and again the elements are found to be merely intensive — intensity of (passive) touch varying with intensity of effort ; yet here it is not to be denied that the touch is related to the effort in such a way as inevitably to suggest a cleft in conscious experience, which has but to be widened and denned for the opposition of self and not-self to become established. Now the point to be urged is that if only object, as bare obstacle to muscular activity of a touching organ, has already to any degree become differentiated in consciousness, a basis is got by reference to which the conjoined sensible experiences shown by analysis to be involved in any perception of extension may begin to appear — not as the simply intensive experiences, of one kind or other, which they are in themselves, but — as constituents of object (as not-self). In point of fact, the development of the two aspects of external (bodily) object — resistance and extension — will proceed pari passu as soon as a beginning of both has been made ; or, to put the case otherwise, body will not come to be perceived as definitely external till it is also perceived as definitely extended (in relation to an extended organism of the perceiver). But the first begin- ning must take place somehow ; and this, upon the view here contended for, is to be sought in that aspect of object (as body) which we call Resistance, rather than in that aspect of object (either body or space) which we call Extension. Apartness — which is another way of saying Extension — needs, in short, for its apprehension that something be supposed already there in which the particular kind of this- and-that meant in the word ' apart ' may be manifested. The mistake of the space-theorists, generally, is to seek for an extension that is extension of nothing at all. No wonder, then, that those of them who take their task most seriously, finding the means proposed insufficient but not exactly considering why, are tempted into transforming these by assumptions that practically supersede the psychological question altogether. Let, however, the 'something,' in whatever vague sense of an experience of resisting object, be first got — as got it can be on psychological ground — and there is no longer the same difficulty of construing as extension other (more complex and varied) experiences that THE PSYCHOLOGICAL THEORY OF EXTENSION. 285 are had in connexion with the first. A base is wanted for the psychological operation. A psychological base is not wanting. The reader has now but to look at the theory of Perception elaborated with so much care by Mr. Ward in his Psycho- logy to see how completely is there reversed the order of explanation here maintained to be the natural and effective one. Like others who have followed the German lead in this matter, but with an independence and a thoroughness of treatment all his own, Mr. Ward first works out a space- theory in the vague, and only afterwards, under the head of " intuition of things," comes across the kind of considera- tions here regarded as fundamental in any psychological doctrine of perception. See, especially, what he says upon the second and the fifth of the "points" which, in the following order, he distinguishes in the complex presentation of an orange or piece of wax — (1) reality (actuality), (2) solidity or occupation of space (impenetrability), (3) con- tinuity in time, (4) unity and complexity, (5) substantiality. Now, certainly, the intuition of " thing " is the culminating fact of perception — so much so, indeed, that there enters, I venture to think, a good deal more into the psychological account of its "substantiality," at least, than Mr. Ward, for all his care in distinguishing those various moments, appears to recognise — but the psychologist is not therefore justified in keeping back till the later stage all reference to the simplest, the earliest and the most impressive of all our sense-experiences in the case. We do not first " attain a knowledge of space" by " movements of exploration," and then, " when these movements are definitely resisted or are only possible by increased effort," "reach the full meaning of body as that which occupies space" (p. 56 a). Rather, as I have sought to argue, we first, through simple and direct effort put forth, get some kind of vague notion of body as resisting, and then by more complex efforts that are found to procure tactile impressions (continuous or discrete, as the case may be) — efforts not interpretable as movements till they have done their part in the work of psychological construction — we distinguish this and that extensively with- in such body, and the body as a whole in relation to our own 286 THE PSYCHOLOGICAL THEORY OF EXTENSION. bodily frame ; later still, distinguishing from such extended body the (empty) space which it fills. In Prof. James's elaborate theory of space-perception, the salient feature is not so much the direct consideration of extension by itself — though it is so considered — as the pro- minence given to questions of visual space, which it is his purpose to solve in terms of purely ocular experience. Upon this, it is not out of relation to the foregoing remarks to end with a certain note of interrogation. The service, indeed, should first be acknowledged which Prof. James has ren- dered to English psychology in forcing attention to ques- tions which it has been too much the insular habit, since the days of Berkeley, to slur over with a merely general profession of Berkeleyan theory. There the facts of visual perception are, in all their variety and perplexity, as they have been made out by the patient labour of so many continental investigators. It is no small gain to have them now brought so definitely into English view, nor less to have them at the same time explained, with triumphant confidence, in the sense most shocking to English prejudice. But the query may not be suppressed : What is, then, with Prof. James and the physiological allies to whom he lends psychological authority, the meaning of visual perception? When, straightway at the beginning, he puts skin and retina without ado on one perceptive level, and applauds Hering's declaration that he, for his part, has ocular sensations not only of the surface-order but " roomy " altogether, one wonders if the thought has occurred to either how ocular sensations are had at all. It is not, of course, with eye only that we are visually conscious, nor again with anything that can be called ' visual centre,' more or less circumscribed as this may finally prove to be, in the brain ; but (keeping, as for the present purpose we may, to physical terms) it is with the brain altogether — a brain that has never been known to develop the functional activity of perception without skin- impressions. People have lived and died without the use of eyes, but nobody has ever grown up with an insensitive skin. How can Hering, then, or Prof. James, with a perceptive consciousness of touches all-compact, say what the eye alone shall in the way of space-perception be able to accom- THE PSYCHOLOGICAL THEOEY OF EXTENSION. 287 plish ? How show that " roominess " — or, for that matter, surface either — which their eyes may readily be credited with beholding and in fact cannot help seeing, is an affair of mere ocular consciousness ? Nor, in asking such questions, is it at all implied that the eye does not give, or rather procure, us everything that is highest and most commanding in our space-perception. It is not even implied that, if we could suppose ourselves reduced to the eye with its exploratory movements as our sole and only means of constructing a spatial order, such a construction might not come to pass — however far removed it would be in character from that of our actual experience. All that is meant is that, dependent as we are for all our basal experiences upon locomotive organs that are at the same time tactile, it is impossible for us through the eye to have a perception of space that is not ultimately, whatever its refinements of discrimination and consequent development of range, to be referred to the tactile base. This is the position that Berkeley took up, and it remains inexpugnable, let the particular ocular conditions be what they may that have further to be taken into account before our visual experience in all its detail is satisfactorily explained. But in the position, rightly under- stood, it appears to be no less involved, as I have here sought to maintain, that the construction of tactile space needs again for its base a prior construction — no matter how inchoate — of tangible object. DB. H. MUNSTEKBERG ON APPERCEPTION.1 Is the psychological function to which Prof. Wundt would appropriate the hitherto unsettled name of Apperception radi- cally distinct from Association ? This is the question to which Dr. H. Miinsterberg more particularly addresses himself in the first part of that remarkable series of Contributions to Experi- mental Psychology which (as noted in Mind, Nos. 56, 57) he has begun to publish.2 The question is not at all new, being in fact as old as psychology itself ; but it has acquired a new prominence of late, in this country as well as in Germany. It has been urged upon us here, in the home of Associa- tionism, that without positing a function of attention, sub- jective activity, activity of consciousness, will (or what not else, so long as the essential import be activity), there can be no scientific understanding of mind, — any more than it has been found possible in common life to speak of mental experi- ence without words of active meaning. The special interest attached to Wundt's similar declaration in Germany arises from the experimental grounds on which he seeks to base it, or — what comes practically to the same thing — from the psychophysical attitude which he desires always to maintain in psychological inquiry. For, if Wundt asserts an apper- ceptive activity beyond mere associative process, it is not that he does not labour to interpret the one as well as .the other in physiological terms. In spite of various expressions which have led others (like Prof. Bain in Mind, xii. 174) be- sides Miinsterberg to doubt whether he thinks it of universal application, it is not really to be supposed that the prime 1 Mind, xv. 284. 3 Bfitrage zur experimentellen Psychologie.

MUNSTERBERG ON APPERCEPTION. 289 champion of the psychophysical method in- this generation is not as much concerned as any of his critics to obtain by means of it the necessary basis for strict experimental in- vestigation over the whole mental field. Now when asser- tions are based on experiment there is the signal advantage that by experiment they can be decisively tested. This, then, is the task which, in regard to Wundt's doctrine, by preference over any other assertion of an efficient activity of consciousness, Miinsterberg has undertaken in the first of his published researches, bearing the special title of " Voluntary and Involuntary Combination of Ideas ". This memoir, like others that have so far followed it in the series, has the noteworthy feature of not putting forward any elaborate tabulation of numerical results, but of presenting these in the most highly condensed form consistent with intelligibility and serviceableness for infer- ence. A deft and untiring experimenter, it is yet about the reasoned interpretation of his results that Miinsterberg is chiefly concerned. Not only, therefore, does he include with all his researches (in their published form) a careful review of previous work done on the subject of each, and develop at length the conclusions to be drawn from his own experi- ments, but he places in the front of his Beitrage an argument- ative statement of the aim and method of his whole inquiry. To those who may have come to think that the proof of recent advance in psychology is to be found in the new fashion of severe numerical presentation, Munsterberg's wealth of argu- ment, often polemical, may seem to indicate a falling-back into earlier unscientific habit ; but, surely, it is not so. There is not yet such universal agreement in matters of psycho- logical principle that all that remains for the scientific in- quirer is to sink himself in special questions and heap up experimental values in bald tabular form. Questions of general principle are still among those that most need con- sentaneous determination ; and if this is to come, as it can now only come, by way of rigid experiment, no prior or sequent discussion that helps to make the experimental test more precise and telling is anything but in place. Apart from a certain disposition to range somewhat widely in argument and perhaps some superfluous repetition, — which 19 290 DR. H. MUNSTERBERG ON APPERCEPTION. it would be well to repress and avoid as far as possible in the interest of an enterprise that has to make its way with readers but is now (after its third part) clearly not going to fail through shortcoming of its author, — it may fairly be said of Miinsterberg's experimental work that it has peculiar value just from being so pointedly prepared by general considera- tion and driven so completely home. Coming now to the direct aim and purport of his carefully planned scheme of research, it certainly cannot be charged against Miinsterberg, however it be with others, that he does not constantly bear in mind the necessity of making no psychological assertion that has not its definite physiological counterpart. While his investigations are declared to be psychological — that is to say, neither physiological on the one hand nor metaphysical (philosophical) on the other — they are yet psychological in a sense that keeps the physio- logical reference ever in view. Not that he denies the pos- sibility or legitimacy of a purely subjective psychology, work- ing with its own appropriate conceptions and hypotheses. This he does as little as he fails to see, from the philosophical point of view, that physiological facts, like all other facts of objective science, can have ultimate expression only in terms of conscious (which is properly subjective) experience. But within the range of phenomenal science, where facts of nerve- physiology stand in obvious relation with facts of subjective psychology, he is most of all impressed by the circumstance that the one class — objective as they are— lend themselves to a definiteness and a continuity of representation unattainable with the other. It is, then, psychophysical consideration which he aims at carrying consistently through, in the interest of a scientific understanding of mind. And the prime question, of course, is how the facts of (subjective) consciousness are to be conceived, for this to become pos- sible. To this question he replies with all due explicitness in his introductory sections (pp. 1-63) on " Consciousness and Brain " : not for the first time, indeed, for he had already faced the question in a previous critical essay (Die Willens- handlung, see Mind, xiii. 436), where lie sought to work out a psychophysical theory of Will in all its manifestations, DR. H. MUNSTERBERG ON APPERCEPTION. 291 low or high. The difficulty is where conscious experience seems to be of a sort that can only be phrased (subjectively) in terms of action. It is not always such ; for there is now what may be called a general allowance, that muscular reaction innervated from the brain under stimulus from afferent nerve is an adequate physiological expression of the simpler kind of psychological experience covered by the name Sense. Such mental aggregates, too, as are plainly of associative origin are hardly denied to be representable by definite brain-configurations, — whatever difference of opinion may remain as to the exact (subjective) analysis of Association. The difficulty, no doubt, is already there, or still earlier at the stage of Sense, in as far as either of these kinds of experience may be held, after all, to import some degree of conscious activity ; but it becomes most truly marked where Volition for personal ends, or Thought as subjective reaction upon the multiplicity of experience that passively accrues, is in question. Here it is that Wundt finds it necessary to oppose to anything that can be called Association a function of Apperception, — which he leaves in general with purely subjective expression, though at times seeking to connect it in a more or less halting way with process of the frontal brain-lobe. Miinsterberg, on the other hand, makes it his express care to see whether the phrasing in terms of activity of consciousness, which so ill bears physiological translation, is as indispensable subjec- tively as it is not denied to be subjectively admissible. By way of analytic inquiry, directed especially upon that notion of conscious Ego or subject to which is ascribed the power of striking actively into the stream of mental occurrence, he claims that not less admissible is another manner of psycho- logical statement for which the corresponding physiological expression is not so far to seek. The problem, in fact, as he urges, is to interpret all that is called activity or change of consciousness as change of conscious content. So inter- preted, there need be no more difficulty (beyond greater complexity of statement) in finding the physiological formula of thought or volition than of bare memory or sense. But to Miinsterberg it is at the same time clear that, in thus transposing the psychological theme for consistency of 292 DR. H. MUNSTERBERG ON APPERCEPTION. scientific understanding, the limit of possible explanation should be well observed. The fact of consciousness itself, with all that it directly implies, — for this, he holds, there is no meaning in seeking a physiological expression. In other words, it is the empirical Ego of psychology — not the pure Ego of philosophical consideration — whose doings it is pos- sible to interpret in terms of subjective "content," and thus render translatable into the other language employed by psychophysical science. There is the more need to note this point which Miinsterberg so explicitly makes, because Wundt, if prone to bring consciousness as an unknown quantity into psychological explanation, has yet committed himself (like others in these days) to the general position that conscious- ness has its physical expression in terms of the collective functioning of the brain (or nervous system). Between the two investigators, it may seem a case where the adage holds true that the half is more than the whole. Consciousness with its fundamental activities of discrimination and assimi- lation (or however they are expressed) may very well be taken as simple assumption not needing or admitting of any other kind of expression, — provided that none of the specific questions of our mental life with which the psychologist has to deal, remain withdrawn from the kind of scientiQc deter- mination that has been found so effective with some. For, now, the peculiar importance of Miinsterberg's work lies in the kind of questions which he is able, from his point of view, to subject to experimental treatment. The point of view has often been taken before, if never, perhaps, with such careful discernment of the issues involved: what no one previously has done is to make so good a beginning of turning it to scientific account in detail. The question being this — whether there is anything in so-called apperceptive activity that takes it outside the sphere of associative process (assumed to be psychophysically intelligible), Miinsterberg seeks to approach its determination by two different lines of experiment. The first is directed to seeing whether, in circumstances progressively more complex than in a certain simple case of reaction where, according to Wundt, appercep- tive activity of consciousness must already be supposed at work, there is not evidence that all that goes forward is DR. H. MUNSTERBERG ON APPERCEPTION. 298 unconsciously performed, in a manner that can only be physically represented. The other is an attempt to bring acts of judgment or choice (as all would call them) so into relation with cases (as commonly described) of mere associa- tion, that whatever psychophysical account may be given of these must be held equally applicable to those. I. The first inquiry makes use of a distinction established experimentally by L. Lange, one of Wundt's pupils, and interpreted by Wundt himself in accordance with his ap- perceptive theory. The time of reaction to sensible impres- sion is found to vary according as the reagent's attention is directed to the impression to be received or to the move- ment to be put forth. It is considerably longer in the former case ; and this being interpreted to involve a specific act of conscious apperception (of the impression) absent in the other case — where the reaction is supposed to follow with the directness (as it were) of a reflex movement — the ' sense- reaction' is spoken of as ' complete,' the ' motor reaction' as ' shortened'. Now Miinsterberg bethought him of seeing how the relation of the two kinds of reaction might turn out in circumstances where the shortening could not be supposed due to the effect of habit — rendering the act (secondarily) automatic. For this he decided to work with the five fingers of the right hand, and get a reagent (Dr. Thumb, as it happened) to respond with movement of particular finger to particular stimulus, and eventually to particular kinds of stimulus that gave progressively more and more scope for what might seem to be conscious discrimination and identi- fication. The apparatus employed did not in principle differ from that used in the simple reaction-time experiments of Wundt's laboratory, and all this part of the case may here be passed over with the remark that nothing in the way of care or precaution seems wanting to the work. Sound uttered by Miinsterberg himself was the stimulus chosen, and the time was measured in thousandths of a second (
